That coin flatlined for years. What happened and how do you know it won't happen again?
If you can know something for sure you don't have half a million marketcap. Big risk big reward, simple as that. ETH has flat for long time before bull run too. Mincoin not even has reached its all-time high, there is definitely only way to go up: fast growing communtity, new devs, new exchanges, mature blockchain. There is no more coins with infrastructure and such a low marketcap.
