There are many including LoyceV, yahoo62278, Hhampuz, The Pharmacist, AB De Royse777 and more whom I would trust with significant money.
But if I had to name one user only, I would say it's suchmoon.

I trust him the most because of his long history here and especially his action to save potential scam when Gleb Gamow account was on sold- https://bitcointalk.org/index.php?topic=4476583.msg40231840#msg40231840

Can't remember now how much he spent to acquire this account as I read this long ago. It could be one of the biggest scams if a scammer would have access to that account. suchmoon purchased the account to save the community.
