BTC over wealth management: question

Hello, i currently have savings in wealth management (averages around 9% a year in recent years) I’ve been interested in crypto for some time dedicating a few thousand into some alts and trading some more degen memes short term but i am considering a serious move into BTC with my savings that currently sit in wealth management (660000 ish GBP) It burns me to see new price exploration and such outperformance from BTC in comparison to wealth management. My plan is to buy in the next bear (i hope 2026) for around 40/50k USD a coin, (i don’t think it’ll go lower than 30/40 and obviously my entry won’t be perfect) I haven’t set aside an amount i would invest, i’m more looking at the number of Bitcoin i can accumulate (i hope around 10) Any advice/help would really be appreciated, if you think any predictions i have are unrealistic please let me know. Thank you !
