I want to bring this topic once again. For the past few months, cryptocurrencies are really off the charts and making waves in the market. It's just that the system itself is volatile. Many companies who have their own currencies are making an investment to the people about these currency, that sometimes, it became a scam. If you want to invest something for your future, I think you should still go to traditional ones, like stock market, insurance, etc. If you only have extra money that you can spare and willing to throw it like it's already gone, then invest it to cryptocurrencies.
