Journalist

Yaroslava Kramarenko has been a blockchain and crypto expert since 2017, driven by a mission to drag virtual currencies out of hype-fueled chaos and into mainstream adoption.

Yaroslava genuinely believes in blockchain and decentralization, but she’s got a no-nonsense take on the crypto market — don’t expect her to spin tales of "Lambo on the moon." More likely, she’ll unpack the tricks of crypto scammers. With clear examples and down-to-earth explanations, she brings cryptocurrencies closer to real life.

Bankrupt Alameda sues bankrupt Voyager

Bankrupt Alameda sues bankrupt Voyager

We have extensively covered this story of “unlove” earlier. The comedy of the situation is that bankrupt Alameda accuses bankrupt Voyager Digital of using the money of creditor’s clients, i.e. Alameda. But the key point is that Alameda itself granted the loan from the FTX funds, which actually belonged to the customers of the curly-haired swindler’s exchange. Like a drowning swimmer, Sam is dragging everyone down with them. Does he really believe that would help them climb up to the top?
