I reckon he might be partly correct...
The professional trader claims that in five years, 99% of all crypto assets will be a distant memory...
If this is true, then a lot of altcoins would have been forgotten by now. This theory, would have been in sequence, at least, cryptocurrency has been existing for more than five years now and if we are to goby his theory, then a lot of altcoins Weser today would not have remained.
Although, I do not dispute the fact that so many altcoins have been forgotten, but going by the statistics of 99% might not tally with what is truly happening to altcoins in the crypto space.
What I find funny , is he thinks bitcoin will still exist in 5 years...
He might be right to have said this. Among all the crypt I currencies existing, bitcoin is the most established. If others are or will exist, then why can't bitcoin?
