This is exactly what I was thinking. Lots of day traders are in the game, especially in altcoins.
I'm not trading because I feel it's pretty hard to state whether there'll be a pump or a dump tomorrow or in the next days. Crypto market is still very young and irrational to be understood, and given the relatively low market cap most altcoins hold, few hands can heavily manipulate the whole scenario.
I'm currently strongly investing in all alternative platforms to Ethereum (Stratis, Lisk are an example), as I believe that when ETH will go mainstream, attention will start to pour on them too, and money will follow.
A minor part of my money stays on GNT, SC and ICN too, projects which I strongly believe in the long term will grow and get the attention they deserve.
I'm thinking about getting into a couple of other ones too, I like to diversify as much as I can!
Stratis I think has huge potential. They have huge B2B possibilities because they are built on .NET. The developers keep mentioning that Microsoft is watching and talking with them. I think if Microsoft finally bites the bullet and completely supports STRAT has a huge growth potential. I get the application of the tech and that is why I invest.
Lisk I am watching because they have a lot of people talking about them. I am still lost on their real world application.
I looks like DASH might become the next secondary AltCoin once Ethereum finally hits the mainstream point and loses some volatility, but who knows. I was reading something about how the smart contracts could end up pushing Ethereum up in price drastically because of a lack of supply once everything is tied up in the ERC20 tokens.
