since 2021 Btt, Aurora is my preferred Altcoin and both are my favorite altcoins. but from 2018 to 2020 Cardano and ethereum are the best assets for me and are among my favorite Coin trading.
Your choice was extraordinary at that time and also right now, but it will be even more leverage if in 2020 to 2021 you want to choose BNB as your favorite Altcoin, I am sure you will get even more benefits that can even exceed the profits at BTT and AOA
