One question I came across is if there are different level of risks for different cryptos? I know that generally cryptos are like stocks, ie you only can lose what you invest; but obviously there are financial products to deal with leverage etc.
I sort of understand that you are trying to ask there will be any differences at risk levels between crypto investments and other investments. The simple answer that will be, 'no'. There is no big differences in risk levels in all investments from crypto investments. All the market are volatile and hence crypto markets are volatile as well and the level of volatility in cryptos may differ time to time but that is the basic measurement for the level of your losses may incur in your investment.
If you invest $1000, the maximum you may lose is the same $1000 even in leveraged trading. There will be no additional losses just because of you are opting for leveraged trading. But, losses may occur more rapidly in leverage trading than spot trading.
