To get rich with Bitcoin, you need to stop dreaming and buying coins during a price reduction and sell after the increase. Well, or earn bitcoins and wait for the price to later sell coins.
Better we mining.use S9, I think if we just buying and hopefully the price increases of course we need more patience.
I do not think that now it is beneficial to mine bitcoin. This has long been irrelevant in the home. It may be advantageous to do this only on large farms
