Sure, mining is great and is the backbone of crypto. Decentralization is key for the future of the blockchain. When you break it down in business terms, find out how much coin each gpu or mining ASIC will yield in it's lifespan and see if the cost is worth it. If you bought an Antminer (which on average yields 2 BTC in total) for $2.800, you will have bought 2 BTC for $1.400 each plus change for the electric bill.
