I'd keep a look out for CombiCoin, which is in ICO until the end of this month -->
https://triaconta.com/Their concept is reminiscent of Iconomi (money invested per Coin bought), but much more solid and attractive imo. DYOR and take a look at their whitepaper - it's solidly thought through and professional.
Best part of participating in this ICO, as opposed to getting their products on exchanges is, you get both combicoins (which can be freely traded in major exchanges) as well as one TRIA token for every coin.
The second a CombiCoin is created and later traded, specially designed software will buy the top 30 traded cryptocurrencies equal to the value of the CombiCoin (not the top 20, not top 40: top 30 turned out to be just right - and also in a specific ratio that was optimised in simulations (for example, 7% BTC, 2,4% ETH etc)).
These tokens make it exceptionally lucrative to invest in the ICO, rather than waiting for them to be listed on an exchange, since token holders get an amount of profit the combicoins generate each month, paid out in Eth.
This means that as long as cryptocurrency is traded with a profit (which it has been for years, without any foreseeable end to it), you get a steady income for every triatoken you hold. I expect those tokens to become very valuable because of this, aside from the CombiCoins which grow in proportion to the top of the cryptomarket as a whole. All in all I can see this becoming a big player in the long term.
Sounds interesting but complicated. I know I am not the biggest genius but also not the biggest idiot, do I get this right? You get a cryptocurrency PLUS a token for investing? And every time you trade a combicoin, you also get a share of the profits from trading top 30? Sorry if I got really lost. I love this idea but have difficulty seeing how it works. I don't want to go and ask inside channel and wait
