I'm not sure if lending might actually be illegal as soon as there are laws regarding the declaration of profit in such cases.. I think that the best investment would actually be holding money for now. The price gets higher as more people are seeking less control over them and better security. I'm in this scenario and I'm not sure right now: invest in Bitcoin only or in altcoins too? I don't trust them that much but $0.1 or $1 invested in a new Altcoin that has potential would hurt my pocket.
