>BTC could go to $0 tomorrow. Suppose the US Gov. makes everyone legally declare their BTC assets as assets and they are subject to taxation etc..

BTC is ALREADY taxed as an asset. If you buy $4 worth of BTC, price goes up 20% and the next day you buy a coffee for $5 that is a Taxable event that you need to record and submit a record of your 1$ gain to the IRS to be taxed. Currencies like the euro ect have an exemption for low dollar amounts of gains that BTC does not currently have. If you hold for a year, you can get the 15% long term capital gains.

>Because nobody is using BTC as a currency

People used to when there were low fees. We will get low fees again, but until then, it opens up the chance for other coins to take BTCs market share.
