The small amount is very good to take the start you have to first learn about all the games and then you have to put in a game which you like the most and with that small amount you have to bet the minimum bets and have to get experience to play that game after that you will realize that how good are you there so then decided that what to do.
I always start at small amount where is more thrill from small into big you learn how you can make gambling for exciting in the next minute nor hour having experience while playing is good to realize them selve that gambling isn't a nice way to earn profit.
small or high amount bitcoin are just the same if you use it for gamble.
the result will be zero profit especially if you are a newbie , you may have fun and get some profit in the early times , but the house edge will never let you win it in the long run , really a bad way to use your bitcoin.
actually there are different amount ranges that will have different results for you.
for example if you are gambling with a very small amount or with a large amount but your bet size is also big, then you will surely lost it all in a very short time because any loss means you have nothing to fall back on.
there there is a medium range where you have a medium amount which makes it better than the first one because you have more money to work with and you have a better chance of winning back whatever you have lost.
and the last one is a very large bankroll. this is the best but also risky. and you should start with small bet sizes to get the most out of your bankroll. in this range you will always have more money to win back your losses.
