Ya know, going back to the beginning of this thread, it never ceases to amaze me how many folks are compelled to beat around the bush..... The user asked which coin would be most profitable for mining.... Just answer the god damn question for f**k sake! There was no mention of buying anything, the question was about "mining".
None. The answer is none.
Think about this, if you bought a certain amount of tokens (with the money that could have been allocated to mining) and the coin the coin goes up 100x in a year, you would only be able to mine a fraction of what you would have been able to buy.
Mining only works well if the coin fails to launch and does mediocre increases.
There are so many CPUs, GPUs, and ASICs mining now that any coin/token difficulty goes up the second it comes up on a radar or gets placed on an exchange. The exception being maybe the first 96 hours of mining a new coin.
