Ultimately, it all comes down to your risk tolerance, mine seems to be low while yours is certainly higher
To be fair for full disclosure I bought all my BTC from $20-$200 and have already cashed out a nice profit so it is easy for me to be relaxed. If the price goes to zero I will have only missed an opportunity to make more rather than having lost something I invested. I wish I could be this relaxed when I'm trading fiat markets, crypto does a weird thing to me where I'm able to disassociate it from money.
