There is one opportunity of make some money. The Ethereum Classic ETC is rising faster, it might be good to invest.
I think it would be quite risky if you invest in altcoin. altcoin coin although it is well-known as etherum. nonetheless all altcoin have a very rapid fluctuations. faster than bitcoin. some time ago the price had reached 0.03 BTC but now a 0.02 BTC
Well, that is just normal in altcoins as a big pump and dump can happen anytime due to majority of them has a low volume unlike bitcoins. However, if you are a wise investor you know how to take advantage in making money by participating in the ICO of a specific altcoins.
I have seen ICO's come and go. I have seen ICO's succeed and fail, more on the fail side I think.
If you have the time to research the ICO's then it maybe worth while but be careful, just because it's an ICO does not mean it will make any profit.
Of course you should only invest on the legitimate coins which has a great volume. Waves, lisk, and the DAO has it and so far of the three lisk ICO has been successful in terms of price but does not mean that the others is an automatic failure as it can pump in the future.
