What are alt coins worth invest in your opinion?
I bought etc and xrp before boom.
There are still of coins which can be undervalued on market and can make huge ROI

iCash it has masternodes and the new dev team just started working on the project and it's under a penny right now.

I think BURST is a god altcoin poised and consistent growth with no ICO like most altcoins and with good volume. Plus all you need is Hard Drive more the better to mine it. Plus it is easy to get your hands on it through promotions and contest on the radio station Burstnation. Which is where I heard about it.

A hat tip to the OP, who is looking for crypto advice: don't listen to folks on the internet pumping a little-known coin.

I would take an independent look at Coin Market Cap, see which coins seem to be gaining long-term traction, and vet their websites and social media for activity and make sure they're a legitimate operation.

95% of all alt coins are a pyramid scheme, so unless you have some insider information then it will befit you to do a lot of your own research first.

I would recommend staying within the top 15-20 coins in market cap, as a general rule. This lets you stay out of the tiny ones which are being spun up and promoted across the internet on a daily basis.
