Someone says what will be my advice for this success of holding for long, then I say keep believing in yourself and in Bitcoin, as it can change your life. With just $50, I'm enjoying the sweetness of having believed in it because I had a belief that it could never go back to $20k at all. Now we're here celebrating. How many years do you think I should hold it for? I'm thinking of holding till it reaches $200K. I deserve respect for believing!! We are 2 that have been holding and took the same trade together.

What you did is extremely risky and you are probably one in a million. The riskiest thing that I've done in trading is collecting all the money and opening a long position on Matic coin on Binance with 10x leverage during the bear market and high volatility. Gladly, Matic started rising and it rose from 0.3 to 3 in a few months.
What you did is very risky when it's done with the whole capital because 1% move of the price in a wrong direction completely liquidates the user. Btw if you had a $500 as a collateral on your futures balance, then this 100x leverage equals to 10x leverage. Did you go with your whole capital or did you have an additional balance on futures? I really wonder about this because if you go full in, then you are extremely lucky that the price didn't go down by 1%.
