That is the biggest discussion I guess going on right now.
Difference is I do think this time it is different:
1. Projects with good fundamentals and real-life uses. Helium, NFTs Defis etc. which is different from 2018. 2. More institutional investing. 3. More accessibility for retail. E.g. more exchanges etc. 4. COVID may have also buggered up the halving cycle too.
This being said though, October this year, I will be putting on my stop losses to make sure I escape if it does go bad.
