My advice if you want to buy now is fine but do not hold your bitcoin until next year, because the bitcoin price is fluctuating. You better play trading than just holding it, it's more profitable than holding it until next year.
Yeah maybe you are right but it is still depend on a knowledge of a person in trading, if they are good in trading then it is good for them to trade but if they don't know how exactly to trade then maybe better save it than losing it.
