Only loose when you sell at a crap price.
In that case, let me sell you some shares in my gold synthesis business. It's a great deal, 'coz you can't lose! Just never sell.
How many should I put you down for, friend?
Depends on what you are investing in obviously. It needs to be something that is developing.
I'm pretty sure the price per bitcoin will be higher than today's price at some point in time. And also that it will be lower at some point too.
Your gold synth business thingy I have no knowledge about so I'll pass.
