I already have BTC, Eth, ltc, Waves, Ripple and Neo. I wanna invest another $100 in a new Altcoin. Which one you recommend?
Almost you covered most of them in the top list in growth perspective. Why don't you choose IOTA?
That too had a good spike now a days and it might pump again future. There are few things you need analyse about their project expanding so that it would helpful to buy them with confident.
Also don't limit the bitcoin as you already holding. Suggestion is to increase the same and try to limit your investments in alts except ethreum because it is in growing stage.
