I won't ever put every bit of money in one investment, and that's just wrong just because you are risking all without having a backup plan. I think I would buy a lot of coins when the price is going to be real affordable.
Finally I have found out someone who is speaking a truth.
There is no point in placing all your funds in bitcoin, unless your target is to loose everything you are willing to invest.
Without proper money management and plan, you shouldn't ever think about dong such a thing. You need to have whole business plan ready, what do you when some unexpected incindent will occur.
Bear in mind that spending all your money on bitcoin would simply make you dependant from that cryptocurrency, because you literally don't have any other investment.
So if the bitcoin price goes down, all you can do is just watch your funds getting eaten away by some whales.
With diversification, you might be able to avoid such a situation, but only if you know what are you doing.
