I believe as long as blockchain technology is used, crypto market will never be destroyed even if all countries banned it and Eth is good Altcoin for longterm investment right now, ETH is around $700+ right now and prices at the market are about to stabilize and the market is green again and there are projects in the market as well. One of the recent projects which I think will never let you down is blockgrain.io. Theyre aiming to automate the supply chain with Grain and later on Fruit/Vegetables/Wool. Its an Australian ICO.
Australia is amongst the largest exporters of food, and there is absolutely no competition. Their sale has recently started.
