I missed the boat in 2017 Bullrun and the subsequent crash taught me lessons that I will never forget and those lessons are deeply seared into my subconscious.
So, I cashed out with BTC at near ATH few days back.
In other words you haven't learned a thing

Back in 2017, $3000 was "at near ATH". I guess you already know that it was nowhere near the actual ATH but simply 2x of the previous bubble top (~$1000 in 2013).
Now in 2021, $60000 is the same 2x of the previous bubble top (!$20000 in 2017) and yet you panic sold your bitcoin because you thought it is like 2017 bubble top

I am not super happy though. If the bull run starts in the next few weeks and then extends over to the next 2 quarters and BTC reaches an ATH of around $200k to $250k per coin, I won't be able to forgive myself.
Another sign showing you haven't learned a thing!
If what you say happens, it won't happen over night. It will take price quite a while to reach $200k and $500k and nobody is stopping you from correcting your mistake and buying back!
At the same time if I ride the wave all the way up and all the way down and lose 90% of the value in the bag, I won't be able to deal with that at all.
Only shitcoins lose 90% of their value due to their uselessness.
Even if we assume the rise has stopped there is simply no way for bitcoin to repeat any of its historical massive drops since we are not even close to being in a bubble. And if price reaches a bubble it would be at $500k which means the bubble burst that follows would still bring the price down to $100k+ which is 70% higher than the current price!
Right now 100% of the crypto I have is in stable coins.
Now I'm 100% sure you have no idea what you are doing since instead of actually exiting the market to something safe you have converted your secure and precious bitcoin to a centralized shitcoin that can disappear any time called "stablecoin"!
extend into ETH in 2024.
LOL another shitcoin.
invest in every new coins that gets listed in Binance
Another sign that you have no idea what you are doing.
