2. You are looking for promising coins that are more profitable to mine than to buy. Mine, hodl, wait for the price increase, sell. That is, mining as investment. But here you need to process a very large amount of information, understand projects, and believe in the market growth.The risks are pretty big to get nothing.
-snip- it would make a lot more sense to simply just buy the coins straight off. That way, you'd have less monetary loss, and you're not degrading your hardware's lifespan.
Usually, you wont find an easy/safe way buy a newly released coin in any exchange, if there's any, it's on a shitty exchange/P2P.
By the time it get listed to a reputable exchange, the network hashrate had already been at the unprofitable level.
The "
buy instead of mining" suggestion is applicable for "
already months from release but still cheap coins".
