try altcoin trading, 20$ btc is enough to start trading altcoin...buy altcoins that are good and sell it to higher price
yeah i think that might be the easiest way of making money with bitcoins as the cryptomarket is unregulated and you can do there nearly whatever you want in my opinion
also you might try making some bitcoin to fiat trading, if you will be lucky it will also allow you to make some decent money in my opinion and that will be really great i think
Yes trading is the best option as it will allow you to make some good profits over a period of time if you can handle the trades smartly.
It is a good idea, but it requires a lot of time. (Put an an, talk with the seller, wait for the banking wire or meet them in person and finally buy bitcoins again).
I wouldn't do it for 2$, but better be working washing dishes or even asking people 2$ for domestic housework (mow the grass for instance).
