It's now 2020, where many exciting events are yet to come. Bitcoin will experience another reduction in its block reward (halving), while Ethereum becomes closer to adopting PoS into its blockchain network. The space is definitely maturing, but the level of demand is still a lot less than it was back in 2017.
Nonetheless, I'm curious to know what's the next big thing in crypto?

The level of demand will go up when these two are implemented, if we based it in history where every halving gets up to new price milestone and I just hope that these two are not different and we will have something great to look forward, this is the best time to buy more coins and see what's happening in the market.
