I - Onchain data from 52Hz Onchain (in Vietnamese)-cut-
Thanks for this information, I did not know upbit's accumulation of BTC can be used as an indicator to judge when the alts season is going to start, well, IMHO alts season is already started a long time ago, but now it will start again, and the time is not so far, I also hope this will start soon, soon before I start to convert my alts into USDT or BTC, As I need funds for some reasons. By the way dear OP, the link you have provided leads us to a telegram group, and IDK what language was that, but after translating that text into English via TG's built-in translator I realized your text is 100% same, means you copied it from that TG group. I am not trying to accuse you.
Just wants to know, don't you should change the color of this text "RED" as according to rules if one is copying the whole thing from another platform then they should change the color of the text to red. Just a thought.
Besides that, I also eagerly waiting for ALT seasons, because alts can give us more then what we can get from BTC only. By the way realizing this fact is initself a hard thing, because I also didn't realized this until I came to heard from some expert's reviews. So, after that I thought I should diversify my funds into many alts coins, and one thing they did not told me, but I have learned is, you should definitely have some of your capital invested in tp 10 alts.
