I'm buying few bitcents every now and then, Not a huge amount but something because I think bitcoin has potential to rise in price.
Yes its okay to buy small amounts, when you accumulate enough you can sell it.
I only Buy
BTC for gambling but all my profit comes from short trading.
I think you need to buy a lot of amount. to get a lot of profit if prices rise. if profits come from trading, why not work full in trading?
