Solo mining is profitable only for fresh coins and it last shortly. In case you have few hundred cards you coul solo mine literally anything and still have regular payouts 
I do solo mining with old coins (many times).
The main purpose of mining is solving blocks. When most people think a new coin is better for solo mining equal to the new coin would have a ton of miner. And it will be unprofitable for solo mining.
Remember:
So, Network Hashrate would be the first thing to be considered.
Sometimes people will forget the old coins, especially the new miners, it will be an advantage for us, right? Back to "Remember" point above.
Calculate these few things to get the most profitable coin for solo mining, Network Hashrate, Difficulty, Block Reward (how many coins you get every time you solve a block), don't forget about block time, and the last thing that needs to check is coin price. and You are ready for Solo Mining!
I'm not asking for you to reveal what coins you are solo mining, just curious of anyone is doing it. I've seen the odd thread in here of people solo mining but seems like not many people do.
I would not recommend you to do it. Solo mining can be used only by those who believe in the opportunity to win the lottery. Now the profit margin of many coins has decreased to the minimum level. This is assuming that you will use the services of pools. The profit margin of solo mining will have a negative indicator. Are you ready to work at a loss?With the right calculations, Solo Mining truly different with the lottery.
Same as you, I didn't recommend for a un-experience miner to do solo mining.
OP - If you want to do it, just learn how to do it, and go for Solo Mining. You'll get a ton experience.
Exactly thank you man i agree 100% and it is definitely great learning experience and alot of us just do this as a fun hobby and finding your first solo block is a experience everyone should experience, and also if people try it and it doesnt work for them im sure theyll just stop there not gonna keep mining at a loss for long so whats it gonna hurt
also quick question for you were do you get your info to help decide which coins you might try mining
?
