When will you sell Bitcoins ??
When I need it, because for me bitcoin is a long-term asset and never panics with significant price reductions
Thats right. Its depends on the owner and the situations. If you really need the money, then go sell it, but if you just wanted to sell it because of the price drops f bitcoin, i think you'll regret it later, because bitcoin will increase again later, it wont die because it dont have competitor. Patiencw is what you need when you're investing on bitcoin.
