Right now, price of ETH is low, is there again rise in the ETH ? I can see eth going above bitcoin because of combination between drop in the price of bitcoin and increase in the price of eth.
I dont think so. The next generation of BTC is LTC. Litecoin is almost same as bitcoin. It has the same mining algorithm, but LTC is cheaper than BTC.
For ETH, i think it is a coin created for investing in startup companies by contributing in ICO.
ERC20 token in ethereum network is created to make the company token before it using the mainnet of the company.
