everyone expects the major bull market to happen later this year starting from october

IMHO it already started. Wait for October and you'll miss the really big gains. Don't want to talk this all day but look at AVA or ORN for example. There was plenty of opportunities to load at 0,5-0,7$/AVA or 1,5-2$ ORN.

They're currently trading at 1,4$/AVA and 2,75$/ORN. Assuming that we already had a +100%, a mad bull run of +500% would equal to x10 in both assets (just because you loaded earlier).

The point with ETH is it still trades around ATH, and if somehow replicates BTC, we could see ETH at 2000$ in no time.

I'm still very sceptical regarding ADA or DOT, I think I miss the 'early run chance'. And they're very high in mcap for my personal taste. Better to load on BTC/ETH and forget... ETH will destroy everyone when finally scales, that initial network effect which ETH has already it's a tough pill to swallow for whoever calls itself a 'Ethereum killer'.
