Let's give an example that everyone knows: $ARB
We immediately write ARB in the relevant search fields on every site.
At the bottom you can see that seed investors bought ARB at $0.005. Good news: It is locked for 1 year. The bad news is that the 1 year lock period is over and investors are getting ARB installment at 200X every month.
Would you sell ARB at 200X? I'm sure everyone would say yes. That's why ARB keeps falling.
