I have a idea deposit 0.5btc for one time gambling once its double withdraw the profit and never turn back
That's a great trick to not force yourself to be greedy. I am also doing the same thing but in my case I only start with a 0.005 BTC bankroll and every time I doubled it, say I get 0.01 btc already I'll withdraw half of it and play again with the othe half and then try to double it up again. So far it works with just minimal bets. I don't wan to bet high.
It is not trick at all. It is being conscious and smart about the way you play. Don't gamble your money away without plan and throw blind bet while expecting to win it all.
Always check the history first so you could expect whats coming in the next round if the graph hits a high multiplier expect crashing at 1.xx or 0 on the future rounds. This is only my observation when i play here.
Do you really believe that rounds have something to common are linked somehow abd you can predict next one by seeing how the last one went?
I believe that you are wrong. If there is a large trend of low multipliets, then the next bets are more likely to be higher because although the 2 games are independent the chance of losing grows less. Think of a coin. The chance to get 2 tails in a row is (1/2 * 1/2) or 1/4. There is a similar effect at bustabit. So yes, I believe that the rounds are linked. You can't predict it, but you can get a greater chance at winning.
