That doesn't really portray why Bitcoin is better than Fiat.
You're misleading other people. Last December 2017, the price was like $19K more or less; last 2018, the price was jumping between $11k ~ $7k; now the price is jumping at $7k ~ $9k. So clearly it's not increasing "every year". The fiat takes more time to increase in value (does it increase? I'm pretty sure, "exchange value" is the one that increases) because it's centralized, while cryptocurrency is decentralized.
Can you prove to me how can an asset be the future? I'm sure Gold, Silver isn't.
Increased supply(?) Do you mean "inflation"?
