Hi @maxg it is purely based on technical analysis. Cryptocoins are now the official new way banks do pump and dump. They just need a web page full of imaginary products like #cardano #tron #nem #iota , few billions in crypto and they are all setup to charge. Welcome to the wild wild west of trading since the Great Depression. No wonder there are a whole bunch of youtubers affiliated to these ponzi schemes.

I feel iffy about Youtuber support for strange altcoins. Bounty programs are an established way for coins to raise awareness- but being paid in BTC or Fiat is straight shilling. I think all bounty programs should only be allowed to pay out in the coin or token they are raising awareness for. You write a 2000 word post about why FooBarCoin is great? Then you should get paid in FooBarCoin since you believe in it so much.
