In the old days, three to four years back I was so obsessed with new coins simply because they are easy to acquire, mining them is easy and difficulty are low, this got me blind so I started mining coins without getting into good research first, I ended up with coins like
1. MarketCash
2. NiobioCash
3. Worktips
4. Spotme
5. Gadcoin
And so on.....
These coins are all dead or useless right now, few are trading back then but I was too dump to sell and buy better coins.
Today I asked myself why did I do that back then, I guess it's because I never knew the difference of high quality projects and why some coins make it to top 100, If you are reading this make this your targets
The importance of real use case
^ This. 2017 you could have held almost anything and made money though. Now....meh...
Tbh, the CMC landscape of the top 50 changes pretty much every year. I think when we see the next bullrun, crypto will probably look much different.
