There is always a bit of luck involved in crypto investment as none of us has a crystal ball. I participated in an airdrop and forgot about it for a couple of years. When I checked, the $2-3 was worth nearly $600 which I then moved into a new defi project that has since doubled it again. In this case I was lucky with something that I had forgotten about but I have also had some bad investments.
I am going to continue sitting on my Bitcoin and Ethereum for a while yet. I do believe that everyone should put a large part of their portfolio into these 2 and then a proportion into other altcoins which are more of a lottery for long term outlook.
