Pool mining -> you will connect your mining hardware/device with others to make a pool of hash power for mining
Solo mining -> you will just use your mining hardware to mine any crypto on solo
Cloud mining -> you have to buy/rent mining hardware which will be located in another part of the world and service provider with send out you coins generated by your mining hardware you have bought or rented with them
To learn more about what actually is crypto/bitcoin mining and many more make a quick search in google, you will find lots of guides.
Thanks to this also, I would love to do that solo mining but I need more time, money to invest to buy some hardware to it. Looking some place also that electricity is affordable and cheap. Because my country is one of the most high rate on electricity because of monopoly of businesses and of corrupt government officials before. I hope things would change a little bit sooner.
Make sure you do all necessary calculations before attempting solo mining.... Solo mining at the current diff is more or less like buying a lottery ticket.
I'm disregarding the purchase cost and the power cost in this example, since those ones don't change your odds of finding a block.
At the current diff, it would take you (on average) 3918 days to solo mine a block using the most efficient ASIC currently available, the bitmain antminer S9 (
ref)
This means that if ~4000 people were running an S9 in their basement for a full day, on average, only one of them would solve a block.
It also means that if you solo mine with a single S9, and the network stays completely status quo, on average it'll take you about 11 years to solve a single block... Factor in the fact that the diff usually rises (it has some dips now and then, but the general trend is up), and the block rewards halve every 210,000 blocks (~4years)...
My conclusion would be that you either have to see your one S9 as a lottery machine and solo mine, or you buy at least 100 S9's, so on average you'll find about 9-10 blocks a year, or you join a pool with your S9 and steadily make ~0.09
BTC/month untill the diff adjusts.
