When is then best time to buy bitcoin and when do you think is the best time to sell?
I think its a great time to buy now but when is a good time to sell (if you have any idea please share)
The best time to buy BTC is when the price goes lower than usual so you get in at a better price then what it was an hour, a day, a week ago, etc. The goal is to get a good trade.
My answer on when to sell, NEVER.
I think that here I completely agree with you. The fact is that to date, selling Bitcoin will be very wasteful. If you are sure that in the future the price will be huge, today it is better to save and not to sell your coins.
