GSR has published a browseability score of #ETF. for several coins. Most are coins from last season, this season only $APT is present. Proves that APT is doing well, right, AE.
My personal opinion, I should just stop at #BTC and ETH, there are too many, let him stick with #ETH forever, it's small but quality is better than quantity. Scarce rather than bluff. The altcoin crowd only helps pump up the diverse market.
BTC - ETH ETF will lead traditional investors into the market, while Altcoin will attract by creating xx account opportunities if you choose the right platform. Then let other people show off, new trends, new technology to give traders FOMO like in the past the previous coins did ::D
