So yes there is inflation with USD but there's also the government behind it keeping inflation down by destroying old money, something else that won't happen in Bitcoin
How about coins that are no longer accessible? Private keys can be lost or their owner can die without revealing how to access them. Less coins, higher price.
The amount of money growing in the total money supply (from debt etc as well as actually printing dollar bills) way exceeds the amount of currency physically destroyed. Look at what a $100 bought in 1999 vs how much that same $100 buys today. $100 today buys a whole lot less fuel, food and rent.
I guess that’s one of the big advantages of bitcoin:
- it’s a deflationary currency and so can be used as a store of wealth in troubled economic times. It’s more likely to increase in value than the USD which we know will drop in value over the next few years.
- it’s not tied to geography and won’t be caught up in a trade war. If the world moves away from the USD as a global reserve currency (as nearly happened when the Euro came along) then the USD will tank. If you are in the U.K. holding pounds really sucks right now with brexit still reducing the value of every penny. Bitcoin, once its stable, allows for greater security than any one geographic currency.
- it cheap to transfer funds if you transferring large amounts
- it has MOST of the privacy of using cash with most of the advantages of using a quick to use debit card.
I agree with the OP though in that we are so early in the development of crypto currencies that buying bitcoin is a hobby rather than a long term investment. I’m very bullish about crypto in general but I’m not putting in more than an amount I’m willing to loose and these days I’m buying a basket of currencies not just holding bitcoin. There is no way to pick the crypto winner or winners today. In face we know that some of the current high market cap coins won’t be here in a few years - we just don’t know which.
