It's because you are using the cryptocoin wrong. They are not means of holding wealth, but as means of transfering wealth.
If I need to transfer EUR from USA to France, I will have to pay my local bank in USD, convert to EUR, pay the transfer fees, and my counterpart will have to pay some fees there too. Depending on the amount, we both will have to explain something to our governments too.
Using bitcoin I just buy some coins, send them, and my counterpart sells them. Nice, easy, fast, and no taxes, fees or government explanations to give.
People keeps bitcoins on hand because it is increasing in price, but they were not intended to be used like this. You can use as you wish, but if the market breaks down, it's all your fault.
