It would be risky to invest on altcoin you barely know since you didn't specify the crypto you want to invest on.Since your seeking for financial assistance on the capital you would want to start on your crypto investment portfolio I will say go for $5000 incase the project is a ponzi scheme.I would advise you to invest on BTC, Ethereum that offers huge profit return for a long period of time.
Ponzi schemes are real and not profitable at our ends. Bitcoin and Ethereum remained the top projects for us, without holding back from doing the necessary movement to stay profitable. Investment speaks for us at our downtime and in the future, we know what we seeks and will do everything to continue pushing for elevated phases. Invest in projects that will never dissapoints us because anything out of the picture means huge losses on our end. It's always encouraging to abide by the rules and do the needful.
