Has anyone ever tried/read somewhere about reverse labouchere for two dozens/columns? I would appreciate if anyone can provide the link of that or explain the methodology(even in its crudest form). If it is nowhere, I would devise one myself.

Randomness is the core of betting or any form of gambling. If it is not purely random and predictable to a large extent the reward on the bet will be lesser. That is true with sports betting but casino gambling is purely random and chance to win is directly proportional to the risk involved.
        Randomness ensures that all silly money management ideas will fail eventually. Randomness makes all skills of choosing your bet go foolish finally.
          Randomness is not infinite though. It mellows usually around 6X of the break even point and crosses that very rarely. Although there is no absolute limit of randomness, it can go wild enough to kill a novice guy with irreversible loss. 

   In nutshell, no randomness, no gambling.

This omnipotent phenomenon of one dozen/column going laggard could be exploited to win huge betting rest of two dozens/columns which are pretty active with a parlay type safe progression, clever enough to handle some fluctuations. One can rather break the bank with this.
            Recently, in a session of mine, a dozen hit after 24 spins and missed another 9 spins before getting another hit. A simple progression player on a dozen could commit suicide getting such bad streak but I made one of the biggest win of my life with that.
              I am very much focussed on exploiting such things in an organized manner. I have got casinos with 10-500,000 units table limits online.Working on it to make it one of the most potent weapons against casinos. This thing did not work as well with EC bets and could take forever to win big, that way. Could be tried against smaller bets than a dozen, for sure.

It is already over $30k. Those who were skeptic of its growth have missed almost 90% growth when it was at $16,600 levels at 31st December 2022. It was near $20k in June 2022. Even from there, it is 50% up. This year we will see $50k levels for sure and a single fortnight can be sufficient to pull this much price. If it doesn't reach a new all time high by 2024, its bubble will bust forever.

As I expected and predicted, it broke the price barrier and getting costlier by more than $1k every day. No wonder it gets all time high before we thought it to reach there.

Any bet smaller than that could go even bad for longer. We have seen the fate of #3 in zumma book of roulette with 15k spins.

I have observed this for too long and hence sharing this with you. This is not backed by any statistical observation or upon any principal of probability but playing the weakest dozen ( a dozen which is hitting at 5/20 or even worse) looks very bad to me. That usually happens when 3-4 numbers of a dozen remains sleeper and rest of the numbers remain either average or below average. Even if a single number of that dozen is hot, it can not help much by itself.
        We all know that a single dozen could remain sleeper for even 40 spins and could reach hit rate of even 6/60, trying that is not wise. Maybe it helps someone playing safer.

There is a strong resistance against price growth of bitcoin at $25k. Once it crosses $30k mark, it will skyrocket. We might see an all time high price within a year and half max. If it doesn't work that way even upto 2024, it will lose its lustre and charm forever and could crash huge.

Remember we keep getting new goldmines and yet gold is getting costlier and scarcer due to its massive demand and value everybody wants to have a bit of it.if Bitcoin becomes a rare and precious asset with international acceptance, I see no reason for it going doomed.I m not so sure about other altcoins though.

With my variance management rules he could have won huge. Bankers and Players both do fine in the long run but people start playing martingale type suicidal idea that can win the least and lose the maximum. Strange to see such people in plenty still.

Bitcoin increased about 35% in January 2023 alone, so far within 26 days. It could be an indicator of its next highest value ever. IF this trend continues even for 2-3 months, seeing a level of $45k is no big deal. Bitcoin and shiba inu, alongwith some other coins have grown to unimaginable levels which had never been predictable. IT is for sure that bitcoin will go scarcer day by day and that factor alone will push its price to any extent. If the entire concept of crypto fails, which is not likely anytime soon, I do not see much threat to bitcoin atleast. Bitcoin Halving is Predicted to Occur on Tuesday Apr 16, 2024.
Historically, the cryptocurrency experiences massive price increase during its halving episodes, increasing its value by 1,263% between the 2016 and 2020 occurrences of this important event.

With the trend, it is projected that by March 23, 2024, a single unit of BTC will have a value of $120,263. In 2009, the reward for each block in the chain mined was 50 bitcoins. After the first halving, it was 25, and then 12.5, and then it became 6.25 bitcoins per block as of May 11, 2020. To put this in another context, imagine if the amount of gold mined out of the Earth was cut in half every four years. If gold's value is based on its scarcity, then a "halving" of gold output every four years would theoretically drive its price higher.
   This is a very unique proposition with bitcoin that does not apply to other altcoins. Many have unlimited or near unlimited supply like XRP or SHIB. They may grow along but not to the levels of bitcoin. Even it is possible that after this halving, Bitcoin does not go down but keeps doing great due to FOMO (the fear of missing out). 21 millions is not a big number when everybody will seek it.

On every halving, bitcoin reached a new all time high that is usually at least 50% up from the last run highest. 2024 is the year of bitcoin halving. Do not forget one peculiar thing about bitcoin. It was the pioneer and all other coins are altcoins. It has an all time maximum supply of 21 millions. Hence, it will go scarcer like diamonds, year by year. I firmly believe that bitcoin should touch levels over $50k by the end of 2023 itself or maximum by April 2024. Let us see this. 2023 will decide its fate, for sure.

Year 2023 is doing great for all cryptos. Bitcoin is about to touch its 52 week high. Year 2024 is said to get all time high of bitcoin and some other altcoins too. What do you say?

I have tried to play both sides with +50/-100 targets and winning in most of the sessions in both ways. Apparently +50 in both sides are taking different timeframes. Below average times for one side is great time for others. I wonder if it ends the game, my way or there is something that I m still lacking. Should I finish both sides for my targets or leave at a good average winning stage taken both sides together? Any thoughts?

Nothing changes the advantage of casino but still winning is possible in the long run with a clear and unambiguous way to play. Regarding compounding of money is concern, that is of course doable. No casino will win you if you earn modestly and your meagre income, even regular will not make them lose big, while other players will keep losing their 100% bankroll, your winning 1-2% of your total stake will hardly impact them. There are plenty of casinos to chose from. These days, I play online live dealers where bet range is insanely from 5 to 75k. If you do not bet too huge, u will be unnoticed.
