I don't really know your points of view, but it seems that what you're emphasizing to, but from my perspective it seems of that you're asking if is possible to start Bitcoin with little or available funds, already I know that if you have your fund's at hand you can start purchasing your bitcoin and hold, and any value you purchase in bitcoin is reasonable one at the moment, because if bitcoin increases the value will not remain the same, so is encouraging to purchase bitcoin with little you have, since you have the passion on it.
