I've seen over one dozen websites believing that BTC will skyrocket in the upcoming years.
The platform I use is Coinbase.
I'm thinking of just buying BTC-USD and just leaving it be.
Any thoughts on this strategy?
Buying BTC-USD using the dollar cost averaging method is still very relevant to do, but don't let BTC be stored on the buying and selling platform.
Whatever platform you are going to use to buy Bitcoins and choose to just leave it on the buying and selling platform without moving it to a trusted wallet, then that is not a positive strategy but a strategy of handing over the safe keys to robbers to take your money.
