In other words if you put 1000 dollars in MASS in May you''re down 650 USD and if you did it in June you're only down 400. Such a stable investment
With this logic BTC is such a useless investment, its up on one day and down on other day. Name any single crypto that is stable throughout in its history. Crypto is all about wild fire. If you need stability, invest in banks.
There is no such thing like stability in crypto, its all about volatiliy. But price of MASS is stable in a sense that its revolving around 0.3 - 0.5 $. It has'nt collapsed so far, this is clear indication that its a strong coin.
Thats not a god advice. BTC price is stable for so many months. You have to do research and find coins that have stable price. There are many such coins who price are stable. Bank investment is crap as it is directly proportional to inflation.
