(you are not mining Bitcoin anyway so only the price of Bitcoin should affect you).
As I said before the difficulty of the mining is made harder when it gets mined more (it also is made easier when fewer people mine it).
The difficulty and the price are the main things that will affect the profitability of mining.
This is definitely the tail end of a boom period, There is still money to be made but it's not as much as it was, People are still scrambling to buy Nvidia cards and they are going out of stock in a lot of places now so rigs are still being built.
All these extra people are going to bring the profits down to nowt IMO, The only saving grace at the moment is a lot of people just use Nicehash so tend to be limited to the big few like Ethereum, Zcash etc some of the most profitable ones are the smaller coins if you can mine them yourself and sell them before the difficulty gets too high.
Skein had an enormous profit a few weeks/month ago but a lot of people caught on and the profits went right down.
A fair bit of the profit going down is due to the price of Ethereum and Zcash as well , a month or so ago they were close to $400 each after a massive boom of their prices, It's since gone to close to half that, So mining 1 of them is worth close to half what it was a month ago.
