Just hold onto 50btc. 1 block. 1/420,000. Then if bitcoin lifts off, you're rich.
I have more and I will hold them for the next 20 years. Because I belive.
But what will happen to the random guy that invested more than he can lose @ 20$? A lot of people will be hurted by this bubble, this is why I don't want to invest now and I call myself out.
If you think this is a bubble, and if you have bitcoin savings, the rational thing to do would be to sell part of your bitcoins on the way up, and buy them back once the bubble pops.
That would help to dampen the bubble.
By "calling yourself out" you are neither helping yourself nor the bitcoin economy.
