Once a decision on Bitcoin investment has been reached, then expect things never to remain the same, because there's going to be a change, at first it may not come as expected, but over time it will definitely looks the perfect way it should, this is almost the same kind of challenge faced when having a business startup, you not not expect it to begin yielding as immediately like that.
For business this can work not only as a way to form their reserve, they can also start turnover in their company in bitcoins. For example, they can accept payments in bitcoins, pay salaries in bitcoins if the staff agrees to it. And basically, they can move part of their capital toward bitcoin. I understand that right now this sounds complicated but if a company has such a goal and they see potential in it, they can try to implement it.
But even if they just decide to allocate part of their profit into a bitcoin reserve, that is also not a bad idea. Because if they have the opportunity for a long term investment and this money will not be needed for business development and expanding their social network, bitcoin can bring them a good profit.
