Now that there is a lot of Altcoin in the market, do you know how many types it has?
You can classify them by different criteria.
For example, you can classify them by the distribution: coins distributed by mining, ICOs or airdrops.
But the best way to classify them is by the technology, which can be PoW, PoS and, an old concept, but only recently brought to crypto: DAG, which stands for Directed-Acyclic-Graph.
