If you refer the price movement in the chart. Even you can start trading on bitcoin and altcoin trading. There are many trading such as yobit, localbitcoins, polenix, kraken and many more.
If you have enough investment amount with you. Check the localbitcoins site and select your online payment option and start with it.
How much would a very small amount be? Because if you ask me, try to first earn a few more btcs before you start trading. Im not saying you shouldn't but gat would give you a lot more flexibility and room for diversifying your altcoin investments. If you use a very small amoubt on a single coin, that maybtake you forever before getting 10% of your capital back.
