I have huge btc in my wallet.
Please share your opinion about this.
Definitely not, you'll end up losing a large sum of money. It's probably one of the worst periods to sell any BTC you are holding. I'd wait a few months if I were you, depending on how much you are holding. Trading is at its finest at the moment, you could use your funds to trade, if you are into risk.
I suspect that the happiest people here will be the most patient guys that did not give up and did not sell their Bitcoins, especially when BTC was on the bottom. Crypto should grow.
