If I compare the dollar with the bitcoin my preference would be the bitcoin in the of course. Profit and loss analysis is required when selecting investment instruments. The risk situation needs to be assessed.
For me, bitcoin is a good investment tool both in short term and long term.
Why would you prefer with bitcoin? The main deal is bitcoin is depending it's price with dollar. But for me, they are both good and the best thing to do is always depend to both of them because they are one of the majority trading first choice of most of the trader. I do also agree that in the long term goal always go with bitcoin.
I totally agree with you. I do not give preference to whom it alone. I consider bitcoin as a commodity or product as you please, by which I earn dollars. And for dollars is already live. This simple and affordable.
