So far, Bitcoin has been the best SoV. Any extrapolation into the future is speculation. But if you have conviction that will hold, then yes, it makes sense to save in Bitcoin long term.
Agree, everything has trade offs, but some sacrifices don't make sense for the problems Bitcoin was made to fix. Permissionlessness is a major core value prop of Bitcoin (Liquid) "...the main benefits are lost if a trusted third party is still required..."
Liquid also doesn't protect sender, reciever, or IP address. Feels like a half-assed attempt at privacy from people like Adam Back who should know better.
You can virtually eliminate any risk of Monero debasement if you only save long term in Bitcoin. Short term volatility is the same for either Monero or Bitcoin.
Yes, wallet sync times are a slight annoyance, but if you prioritize privacy + self custody + permissionlessness it really isn't a big deal. Usually it is several seconds. Try Stack Wallet or Stack Duo wallet. Seems to be optimized somehow for quicker sync times. Even Cake Wallet was quick. Noticed it was significantly longer using Monerujo for whatever reasons.
There is an improvement coming down the pipes soon for lite clients to eliminate sync times while preserving trustlessness if you run your own node. Seraphis upgrade will also further improve sync times without it.
Monero shines in it's default layered privacy, simplicity, fungibility, and low tx fees. Much better MoE imo. Because Monero doesn't have RBF, it can also do 0conf "instant" txs for small payment relatively securely (99.9%)
