Do not sell bitcoin at this time, but buy more at this time, so store as much bitcoin as you can. Sell it on Dec. 16 - Dec. 17 when it peaked.
Yeah, bitcoin drops as of the moment, so better keep on buying bitcoin. I really have a strong feeling that before the year ends, bitcoin price will reach to $20,000 and I can't wait for it to happen. Anyway, why did you advice him to sell it on Dec. 16-17? What does it mean? Do you think its price will increase to 50% of its price now?
Sell it right now seems like the bubble has exploded and many whales are paying attention to the ethereum. So sell bitcoin and buy ethereum right now.
Well, I suggest to hold it. But it's much better if you buy ethereum also if you have enough money.
