Many altcoins are dumping ground, after the project is launched people invest massively on it, they will carry out a burn and the burn will have no meaningful bulls
This is why you shouldn't rely on what project teams say about burning after launch. Look at the usecase for the project before you put your money down on it. If the project is on an already saturated area, steer clear. It's going to end up as junk and then get abandoned. If it's on something you feel is unrealistic, you avoid it also. Stay moderate.
...then àfter a while the project became dormant like one and only Africa project called "wakanda" I guess many are victims and aware of this falsehood and fake project.
Right from the word go, I knew Wakanda was a scam project just like the one before it Zugacoin by another African called Sam Zuga. BTW, so you know; Wakanda isn't the only crypto project by an African. There are several others.
Please which altcoin is currently the hotcake with bright future ahead?
While this will be very hard to point out, I will advise you to only invest in altcoins with reasonable blueprint and roadmap. If you can't stomach the loss that may result from such investment in alts, it's better to stay with Bitcoin.
