Bought 1BTC with inheritance money, I am scared

I (29M) got 400k inheritance money weeks ago. I have no investment knowledge so I spent all this time just reading up on different investing strategies to grow this money long term and hopefully be able to retire early. Finally settled on investing a large proportion in BTC and the remaining in world index fund. Bought 1BTC worth of IBIT ETF, too scared to buy actual BTC because I am a very careless person and will for sure lose the wallet details one day. But I am also scared that maybe the IBIT fund could one day just randomly collapse and all my money is gone. I feel a little uneasy because I suddenly got this huge sum of life changing money and I am scared that I am being too reckless by going so big into BTC. I have read up alot on BTC origin and how the system works so I am praying my investment strategy pays off. But what if we are all wrong and BTC eventually crashes and collapses...

Also I missed the dip, oh well...
