I'm very suspicious of the prices for some of these more exotic coins. If you mine something like Golem or Pepe Cash with no name recognition, how do you find a seller? The big exchanges don't sell them and finding a buyer yourself is very time consuming. Seems like you're likely to end up with a lot of cryptocurrency you cannot find a buyer for and a lot of wasted electricity.
Were you speaking in hyperbole? I don't even think you can mine any of your examples but lets entertain it:
Golem has $3,000,000 in daily volume and is listed on 17 distinct exchanges (separate sources of liquidity, some of which are on the same website)
Pepecash as upwards of $40,000 in daily volume and is listed on 4 exchanges.
You are going to be making pennies to maybe a few thousand dollars daily from mining and you think there is a liquidity problem that is even applicable to your low-income class?
Shapeshift still requires a buyer on the other end, though I'm not entirely in agreement with the op. Seems like most relevant coins have some real volume
I am just pointing out that you do not need to go "find a buyer yourself" like op suggested. I agree there is a lot to be suspicious about with new coins/tokens.
