As in most technical domains, evolution in the crypto industry moves in waves. The first wave was the building of layer-one blockchain solutions and infrastructures like Bitcoin (BTC) and Ether (ETH). The second wave was the ICO boom. As this draws to an end, there have been multiple speculations on what the next wave in crypto will be.
Some predicted that security token offerings and initial exchange offerings would be the next big thing, but this did not come to pass. Others believe in layer-two scaling solutions like Plasma and the Lightning Network, which, lately, have proved to be critical solutions due to high network congestion and Ethereum’s gas fees hitting a new all-time high each day. Those solutions, unfortunately, are still several years away.
