I think it is a good long term investment to buy bitcoins
There are a lot of risk factors here that you gotta keep in mind before you decide to buy/sell/trade bitcoins
Don't invest into anything if you can't afford to lose
it's good enough if you decide to hold in the long term and believe in the future of bitcoin prices will rise.
hold bitcoin has no risk, when you are able to buy at a low price, and only requires extra patience.
any ways to grow bitcoin always have risks, you have to take risks to get it, or you do not get any at all because you are always afraid of the risks.
