Lets face it
Crypto is not like SP500 or Forex.. and this is exactly why we all are here.
you won't find an index loosing 50% in 4-5 days unless it's going bankruptcy, it only happens in crypto and that's why we love it, because when we can catch a move like this we can get 50% on our money.
but ask yourself, where does that money come from? Future, poorly educated traders, long term investors.. and what does it take? Patience.
