So you mean you want something like 2017? which at that time investors invested in all altcoins blindly so that all the altcoins had an increase in price but in the end many altcoins ended up being a scam, remember my friend, investors have learned a lot from those mistakes and now only top altcoins will be bullish.
This. The market in 2017 and 2020 is really different and most of the people in 2020 already understand about altcoin in depth compared to 2017 where everyone think alt is the new btc everytime a new one emerging.
Can't expect the market to be overly bullish like it was 2017 but I would expect a steady bull run by 2021 but not as crazy as it was in 2017
