I think Bitcoin should be classified as a currency instead of an asset, at least in the USA this is something that needs to be changed.
Now the IRS is demanding taxes between each trade, because cryptocurrencies are seen as an asset, so each trade between cryptos is seen as a taxable instance.

I really hope that all cryptocurrencies would be exempt from taxes on each trade, just like with Forex.

It's better in my country, Belgium, as crypto is only taxed when it's exchanged for fiat. You pay a flat rate of 33% on taxes on your profit.
