I'm not a pro. If we remember how the crypto market in 2017 was very good and maybe 2017 was the best year if we compare it to 2021. In 2017 almost all altcoins moved well and it was very easy for us in terms of setting a rhythm in trading. In 2021, almost everyone can't set a trading pattern.
I actually feel the opposite in 2021 because I can more freely manage my trading patterns this year than in 2017, you can see the very big price difference between 2017 and 2021 where Bitcoin itself has experienced twice ATH in a year. this year while in 2017 there was only one ATH, so this proves that this year has been much better than previous years for cryptocurrencies.
