unfortunately no, it is not enough if we are speaking about good business.. but it is enough to buy a car or even to buy a flat..
which is a very nice outcome for a hobby, don't you think so? ))
and if bitcoin will cost more, then maybe I can think about a house ))
Now, I also do not have enough Bitcoins to start the business. I am planning to open the store and/or deal with clothes. That is why, I am going to trade further, to invest in BTC and wait when they grow.
