A crypto asset is an asset issued and transferred on a blockchain: Bitcoin, Ether, and thousands of tokens behind them. On a trading account you rarely hold the coin itself. The broker quotes a contract, BTCUSD or ETHUSD, and you trade the price without touching a wallet or a private key.
Two things set the class apart. It never closes: crypto is priced every hour of every day, including the weekends when forex and indices sleep, so a position held over Saturday is live the whole time, with no Monday gap to open into because there was never a close. And it is volatile: daily ranges that would be a memorable month on a currency pair are ordinary on Bitcoin.
The SEC's investor site calls these assets highly speculative and reminds investors that the platforms around them may lack the protections a bank or a regulated broker provides. On a regulated broker account that platform risk sits with the broker rather than with a crypto exchange, but the price risk is intact. Leverage on crypto contracts is usually capped lower than on forex for exactly that reason.
A strategy tagged Crypto on Javlot trades those contracts, and its drawdown history should be read with the volatility of the underlying in mind.
