I have been hearing that even major altcoins are gradually losing its value.
For long term investment purpose, no more investing in major altcoins recommended?
Btw, has anyone experienced BISPEX exchange known as its insurance funding?
Let me start with one quick note - no one can recommend you to invest or not to invest, because it is strictly personal decision, so yeah.
Imho most of the altcoins won't make it through this decade with positive value gain results.
So you got to make sure what you are investing in - we are not in 2018 and market is showing signs of maturity not following btc all the way.
Each project has potential ,but you should believe in their results.
