I'm actually quite optimistic with BTC breaking the previous ATH, BTC reached 69K during the last run. 100K is an achievable target, whether by 2024 or later.
Most people got burnt when crypto crashed, the regulars in EDMW crypto thread was trading NFT and Altcoins instead of DCA more BTC. So now the thread is pretty dead, unless crypto craze picked up again.
I used to join those telegram/discord crypto groups but i quitted all of them. The tribalisms are rampant in the cryptocurrency communities, I avoid them and those that called themselves BTC Maxis, it's impossible to have a proper discussion with them.
And yes, please keep your BTC in your own hardware wallets instead of trusting a third party to hold them for you. I split my holding across a few accounts and only have small in CEX for trading shitcoins.
Also, from your above replies, I assume you haven't cash out large amount recently? Do update yourself on the new regulations MAS imposed on the exchanges. It used to be easy to withdraw large amount but past year I kena AML-KYC twice ( StanChart and Gemini )
