The more you survive in this crypto world, the more you start considering it a "big charade"... The thriving projects are those who have nothing to offer and they are 100% rolling on pure "hype", no real development, no real product or use case (not even a plan to put up one)...
Those coins with crazy volumes are most probably some wash trading bots and/or the project owner injecting money, buying his own coin to make some volume and gain visibility.
Exactly, obviously you can do washed trading if you had money from scammy ICO or sold masternodes with 20k-30k in advance, you have money to pay services and make it look the biggest and promissing project
, but like I said, people don't learn from past, are lured by this ingenious scammers and when they realise is too late, well ... we all know the outcomes, the consequnces, sometimes tragic ones.
Rarely, you see a person ask in chat groups about the whitepaper and project purpose or technical goals that team what to achieve and currently working, good sense questions after all ..... only what price it's, if it's minable, on what exchanges is selling listed.
Seriously, that's all what blockchain is, gambling and speculations about cryptocurrency value?
