Crypto journey is at its very beginning, but rarely the first technology, product or commodity (btc in our case) manages to remain in the spotlight over years. Watching the market carefully will help in predicting and catching new technologies, coins, etc, that may become new btc, eth and so on. Crypto is very far from widespread adoption. Just ask your parent if they know how to deal with crypto, and you will understand that mass market requires utmost simplicity and security.
