It depends
if you have 2 btc or more a 10k swing in price means you lose 20K
hey you had 2 btc at 109k
it is now 86k
you lost. 2 x 23k = 46k
that sucks and is stressful.
Capital size makes sense as with bigger capital, your management is more stressful, and big hedge funds for example consider that their management is successful if they get small % in profit. With smaller investors, they don't see it as profit if percent is too small, as with smaller capital they want to have bigger profit percent.
but 100 bucks on 1000x leverage you only lose the 100 so what .
of course if you swing really close to the 1000x payoff number and just miss it by a dollar or 2
that also sucks but you still only lose the 100 you bet.
This is still dangerous because you can think that you lose only 100 bucks, but if you continue this greedy bets you will lose many times and sum up your total loss can be very big after a long time. Finally it won't be better than the first example.
