wow....man sorry about that.... Well, I'm not the crypto expert. I know enough not to mine it anymore. I think their are some new rules in the US about
claiming mined coins on your taxes as income even though you don't cash out to USD. I haven't been interested at all since that..
Here are a few links to some main sites:
https://coinmarketcap.com/ This site is a decent one that were tracking prices with while doing some coin research.
https://www.coinbase.com/ Buying selling and cash out
My experience while mining, well kind of a fun hobby. But also a lot of work. I still cant understand how it totally works from a technical approach. Seems like a scam.
used coin base to cash out the few hundred I made.; And really just did this a project to see how the whole process works.
And, yea it was not worth it. I ended up just using NICEHASH (which really pay's worthless amounts) then stopped completely
when I was just braking even with the power bill.
For mining I was only doing limited CPU & GPU mining. Also only bought stuff I could resell or use for other purposes.
A very cautious approach to say the least...
Actually, I made a lot more money buying and reselling computer parts on Ebay that I wasn't using anymore or ended up being extra parts from the mining rigs.
ASICS are the only way to mine anymore; but its risky if they hard fork the coin against your model. Then it's useless.
One thing that could pan out is if they could develop an FPGA based miner that was efficient and cheap. That way they could be reprogrammed against the hard fork.
But that's still a ways off as far as i know.
But, If you still want to just buy and sell Crypto,
you could just wait for Bitcoin (or any of the top 5 ALT coins) to dip again, then buy. Then be patient. and wait, and wait,...wait some more....then sell when it peaks again.
Well, I should say if it peaks again....
I think the low was at around $3700 (1 BTC) in DEC 2018 then spiked in July 2019 around $1200. The hard part is knowing if you will loose all your money or gain some.
So, yes its just like gambling or the stock market. Another thing, is all of the 2700+ ALT coins (like Grin) always follow the BTC price (with a few exceptions)
So if you buy LITECOIN,ETH,GRIN ...ECT that price will follow BTC (BitCOIN) So if you really believe in one of these coins, and they pennies....then buy them.
Me, I won't. I think its a whole scam. most of these coins will fail. and their probably will be only 1 left. Like a world money system.
But its a rich mans game mostly. They pull the Crypto strings and manipulate the market.
Like I said; I'm not the expert on this. Just my venture and testing far enough to know that I won't
ever try to mine again.
Simple rule; never spend what you cant stand to lose.
I hope it works out for you man,
may God bless your ventures.

EDIT: Looking at
https://www.asicminervalue.com/ I see why you're looking at GRIN,
Profit per day and short ROI. But you have to remember as time goes on, the profitability will go down
because the coin difficulty will go up; and also just may loose value. Look at the history graphs on a lot of these previously "hot" coins,
they don't last forever. For example, you used to be able to mine BTC at home, now the difficulty is so high it take 1000's of ASICS to mine.
So that ROI will fluctuate a lot also..
