this may not be a big earner but sure good to expect something in the future.
I did this to my 1337 and some POS Coins. But I have some problem,since my coins grows in Staking and when the time that I am about to convert back to BTC the price is low and sometimes to the point that no one is buying. And on most coins, it seems that price are constantly diving. Hope I am wrong on my assumptions and observations here.
There are always risk in any investments or how to grow our BTC's, just always be cautious and always be informed.
You are not wrong. Majority of the alt coin have their values dropping non stop. Only a few are able to make it. So it is really not safe to invest in new alt coin even if you are very confidence of it. The promise made by the dev is all nothing but thin until it is proven to work.
