Currency has always lost whether it's gold sinking to the bottom of the sea on a ship or somebody throwing out a hard drive with thousands of bitcoin on it and spending years trying to get them to let him dig in the dump to find it. Coins will get lost. Some estimates are saying about 0.5% of the supply woyld be lost per year. If that's true, then our current inflation would be about 0.3% per year. That is still better than any currency in history, including gold, which the World Gold Council estimates inflates at about 1.5 to 1.8% per year. It's fair enough that we have different strategies. But if you want to hold Bitcoin, so be it. But perhaps you should consider spending in Monero since it's fully private.
