In my opinion, yes bitcoin is a good way to invest your money. Bitcoin price is increasing fast, and you can gain a lot of money through it. If you just let your money into your bank account that interest of gaining or earning money is very low, so if you try to invest some money into bitcoin you can see that your money is gaining and you can obtain plenty of money if your invest become successful or if bitcoin price becomes massive.
Including with the massive is the risk and dangerous too. The market of bitcoin is too much volatile which could turn into nothing in 1 week or 1 month. Knowing the risk of your investing is the best way to prepare for everything.
