This is where it gets a bit interesting. While Merkle Trees are great for ensuring, immutability, most cryptocurrencies need more than just that. They need to have a way for records to be inserted into this immutable ledger and an incentive to keep adding records to the ledger. This is where Proof of Work and mining rewards come into play, and this is where a lot of altcoins (non-Bitcoin cryptos) have a lot of different opinions. A decent amount of work has also been put into making sure that there isn't an incentive for a miner to mine on two different chains (and cause the ledger to fork) and other concerns.
