This is a good decision, first understand the currency you want to buy, do not rush to buy, this is my advice, I wish you good luck...
For me starting trade with small amount is good for all of the newbie in trading, why? Because if you are a newbie in trading you can always practice do trading and be an expert in trading even with small amount., and if you are a newbie you are using a small amount it is very great so you dont even need a big amount to learn or to do trading.
