I guess we can say that 2021, has started to be a Golden Year of crypto already, and so far we have seen good results, bitcoin breaking new all time high, and some solid alt coins also established their highs.
So let's see how far 2021 will take us, bitcoin was projected to crossed 6 digits this year, DeFi, NFT, staking is going to be big as well for alt coin market.
2021 has been crypto's best year yet. Still, I still believe 2017 is the "Golden Year of Crypto" because it was a time when crypto/Blockchain tech finally hit mainstream adoption. It was the "starting point" for crypto as it became recognized by many people worldwide. My guess is that each Bitcoin halving will have a very positive effect over most cryptocurrency's prices on the market. 2021's surge is mostly attributed to the Bitcoin halving of May 2020. Who knows if 2025 becomes even bigger than 2021 for the crypto/Blockchain industry?
Nonetheless, the ever-rising popularity of crypto/Blockchain tech tells us that it's here to stay. There will be times where everything is reds and roses. But there will be times where everything goes bleak, leaving you desperate in the short term. It's always important to take advantage of the hype surrounding the market at certain times, in order to secure your financial future. Once everything goes down the drain, you'll be able to buy more coins at cheap prices to stack them up for the future. No matter which year it is, crypto will stand the test of time as a decentralized version of Fiat in the mainstream world. Just my opinion
