If you are not a part of the solution, you are a part of the problem. 0000000000000000000000000000000000000000000000000000000000000000000000 Like Bitcoin, most PoW coins still require expensive mining equipment such as GPUs, ASICs FPGAs or powerful CPUs, also generating high energy costs and environmental heat that is beginning to be a serious problem for our planet. To achieve efficient mining you need a large investment in hardware equipment that will be difficult to make it profitable depending on your energy costs.
On the other hand, alternatives such as PoS, dPoS cryptocurrencies or similar variants have appeared in the market through Masternodes, etc. This type of cryptocurrencies are based on the concept of holding coins, usually requiring a lock period of the coins to receive rewards or demanding certain days of maturity through which you have to imm- obilize your funds, etc. These systems cause that sometimes high investments are needed again to assemble and maintain the Masternodes, they cause costs in servers, as well as that there are barriers to entry in terms of the amounts of coins and time necessary to perceive profitability. Again it becomes difficult to make profitable these investments, cause the ROI to become negative in most of cases. |  000000.0000000000000000000000000000 |
