Yes, certainly. Look at the Bitcoin price now. It is low enough to buy. It will rise again soon when many people realize that.
I will wait because not sure about rising of Bitcoin right now. Of course it will rise but after sometime. Bitcoin already so high and have to be corrected soon
Increased price of bitcoins, that is are fact from issued a new coins by harfork. But it was cancel for segwit. So bitcoin probably will be drop more if some one trying sell a whale funds. But on other side, a crypto bitcoins has tried used for a few company like amazon market. they have a bounty 3 domains about crypto. Then how about put your coins on this situations?
Placing all funds into bitcoin is not a good idea, because we can't says if the bitcoin value are continuously increasing in the market. But I placed some of my cash into my wallet because it seems price of this bitcoin are going to $8000.
Maybe the better I can do to assure my income is, I just roll over it when my cash earned income into bitcoin.
