as i am a newbie.. i know nothing about trading... what should i do to start trading and multiply my btc.. guys please help me
first you need some money to start trading, bitcoin is okay for trading but you should try to trade etherium too as it is pretty new currency so you might earn a lot from it
then buy any currency when it is cheap and sell when it is expensive, i think this is the main rule for trading, don't be greedy too and don't wait for very huge price rise
