Many cryptocurrencies have found ways to economically incentive "full nodes" without being subject to sybil attacks (one actor pretending to be multiple computers). They do this by requiring the node to have a balance of that currency, and lets them earn as miners (making it prohibitively expensive to sybil). Similar to proof of stake but different. This makes their networks more secure quicker as well as turning nodes into investments in themselves. The amount of that currency you can earn in a year is the yield. This promotes price appreciation on the markets, and for those fearing mass dumps and market corrections it is prudent to realize that node operators all have different time horizons, just like any dividend investor in stocks. This is all complementary to whatever else you would like to use those networks for. With yields being around 8% annually, there is plenty of room for other market participants to discover these networks and accept lower yields. Key words to look for are Supernodes, harvesting, masternodes, staking When any network with those things become valuable and liquid enough then ICOs can happen with those currencies being the funding mechanism for the next leg up. Each of these phenomenons have to be evaluated individually, for their interesting and their most dubious aspects. Yes many ICOs are organizations with no more backing than the blue skies of Kansas, but they don't have to be dubios. It helps to see the ecosystem as a whole, and this ecosystem is a new evolution of capital formation.
