Honestly I like to stick with basics IMO its the same old decentralized barter trade method before ppl started to use currency except you dont have to deliver it physically and face possible misfortune of being robed, goods degrading or being damaged during the transportation.
Looking at ICO fenomena it allows everyone easier to became an investor without any geographical discrimination or disadvantages.
Crypto is still in that early stage, we know from history that barter worked and was used for some time until it evolved so will crypto.
