We know the setup for mining a bitcoin will cost you a lot now, so do you think instead of buying a setup just use the fund to directly buy bitcoin?
Neither. Altcoins are on the rise finally and investing in bitcoin won't be a good option as the price has been going down from the moment the fork got suspended. It would be better to make some short term trades with specific altcoins and quickly benefit from it.
Mining rig for bitcoin cash would be extremely profitable as bitcoin cash is of the latest trend now.
