1 miner can mine very little bitcoins, it is not worth for electricity, you should make a huge mining factory to make more profit. Mining at home is unrealistic to be rich.
Again, i already have said that i don't want to earn. I want to support Bitcoin network and i wonder do my 1 miner would help or i should leave everything to big miners.
Just do it. Get your own miner and either:
1) solo mine
2) point it to a non-Chinese pool of your choice
Whatever you do, if you want to support the distributed philosophy of Bitcoin, don't join the moronic sheep and point it to a high-hash rate pool because you want frequent payments.
