Judging by all means, we need to wait for progress from ETH, the team is working on improving the network, now it is impossible to imagine trading in pairs without ethereum. It is everywhere, that's why it will be obligated to grow, I think so.
It will be very difficult for Ethereum to prove its first place among Altcoins, after the release of TON. I say I think its realistic to buy a telegram coin even when its capitalization is above 7 billion dollars.
