Which ccy u look at now ? I like stratis that I buy the story. Ripple is stuff that should not be touched. The story is nice but the price ........ I was trapped in this.
Investing cryptocurrency is kind of gambling. Just use small amount to play play is fine. But cannot treat it as investment.
They are using blockchain technology. In fact, we may buy a physical wallet to store it. It's similar to a record in a bank. Lot of central banks are studying this block chain technology. In the future, we may see fiat currency in this format to store. Of coz, there are lot of cryptocurrency used to trap money. So really need to study one by one. And only test it as mark six but not investment.
