If you are to say that Matic has been so disappointing, what will you say for coins like EOS and Wave? They are among the projects with their own blockchain that I'm so disappointed in.
Most altcoins are disappointing. You can see how those men coins pumped this year. There are many altcoins that have linked like that in the past. Most altcoins can be very disappointing like. They will pump it and dump it and move to another altcoins. Nothing more than gambling about them.
Matic has been making some effort to upgrade and meet the demands of its users, which is a good sign. It's just a matter of time before getting back to their ATH will be achieved. Let's first watch how this upgrade will go, which will determine how seriously investors will take it.
I will advice people to be careful of altcoins. This coin may not get to all-time high in the next 19 years or more.
