If you had to convert all your wealth to either Bitcoin or gold and keep it there for 10 years, which would you choose? Keep in mind the fact that Bitcoin has only been around for 5 years, and could be fundamentally different in any number of ways in 10 years.
so should you buying when you are nearer the top as you are stating with bitcoin or nearer the bottom as in gold. peak gold price was only 4 1/2 years ago.
I predict a bitcoin pump pre halving then the price will fall off a cliff when people realise that nothing has changed and bitcoin has stagnated. I reckon around $280.
Mass adoption has not occured and there is more and more talk about regulation in Europe, when exchanges start to close and people loose their bank accounts for trading bitcoin it will harm the price.
As stated previously, no one has a crystal ball so we just have to sit back and enjoy the ride
