The question is whether I should create one asset or many assets.
You will not be creating any asset at all because nobody will send you money. At this point it doesn't even matter if you're a wannabe scammer or a wannabe fond manager. You've been trolling this forum for NINE WEEKS now and you couldn't come up with 100 USD of your own. No one is going to invest a single bitcent in your "fond", even if you miraculously succeeded to get on the GLBSE. You've disqualified yourself in every imaginable way. Get real.
