Slightly tells me that I know bitcoin from this forum around June 2017,
But I haven't kept up with the crypto world for a long time due to my busy business and boredom with the price of BTC in 2019.
So I almost forgot all my assets until there was one. the thing I think is my stupidity, I omitted my Trezor which still contained around 9 ETH at the time I bought ETH around $ 700 in mid 2018, and ETH keeps dropping so I ignore it.
Long story short I want to start from scratch I want to ask the seniors who are here.
I want to start trading again. Could you please give me some advice so that I don't go through things like a few years ago.
You can leave your regrets and start from a scratch. Actually, it is a good time to enter an investment considering the fact that the market is currently experiencing a bloodbath. As you get the chance to buy from a low price and you know you can wait and persevere, you should not miss the opportunity once again. Do not repeat the same mistakes you had back then. There are a lot of people who didn't even had the opportunity of learning about crypto yet you mistakenly thought things wouldn't get better anymore as you got from the price last 2019. If you don't want to regret again, start right away while you still can.
