You should sell them right now,and when the price go down then buy more.
Its a common method how to earn btc in easy way. Buy low sell high.
i think bitcoin will never go down and i am sure bitcoin will rise more its price because i also never sell my bitcoin because bitcoin is very much stronger currency now.
I agree. Selling now will be a regret, Bitcoin is only growing. I don't know anybody who has used Bitcoin in the past, and has ceased to do so.
Bitcoin is always rising for now its impossible that we can see huge price decrease these days.
The reason why the price is keep increasing because japan was legalized bitcoin in their country that i think more people in japan will be interested in bitcoin and more company from japan will use bitcoin. so i think the price still not yet finish it will increase more soon like you said people who are selling bitcoin will regret soon..
If we talk about purity, then I earn bitcoin and spend it in very rare cases. I'm trying to save as many coins as possible.
