$50 is unlikely, but I think it's probably going to be $120, $120 is probably the final price of eth, $120 is probably a good purchase price.
It is very rational seeing that eth has no limited number of coins. There will be inflation. While the gas price is too high. People tend to move to new smart contract like achain, neo, and etc, and eth forks. The tokens of eth created are too many. The network is so heavy with them. Useless coins or tokens are created everyday while the dex market is growing. Dex market itself causes new burden of network that increase higher gas price. Yeah, developers are looking for alternatives, when the dex markets of new eth alts are created, I think, there will be high inflation of ethereum.
