masternodes or mining

master nodes are good as they take little electricity and it can support a network by lots of people also it causes coins to be locked so there is a financial incentive for master node hodlers to be sensible and not to break the network or try and bring it down

mining is centralised ish some like btc you need 1000s to get started and the cost on the environment from electricity is huge also it is expensive and increases transaction fees the lower they are the better the chances of allot of people using it

master nodes are good as it allows cheap transaction and allot of them to be done second but it is less secure than mining and it takes some coins to start off mining is less and will cause btc to fall behind master node because it is more expensive and less beneficial for people using it the successful coins will have allot of transaction per second and cheap fees as well as being secure.
in conclusion, master node coins will be the future of cryptos

feel free to donate :)
