There are many methods of trading with bitcoins.
Do not worry if you have a small amount.
The method which I am mentioning,
May or may not be successful,
But you can try it with a small amount
You can purchase alt coins or crypto currencies like black coin,ETH etc .
The coins of these currencies are cheap.
You may buy them and wait for 1-2 years,
And see if there is a price rise and sell them.
6 years ago bitcoin was also nothing.
Infact one guy offered a pizza shop 10000 Bitcoins 5 years ago.
Only because bitcoin's price changed in 5 years doesn't mean that other, new and small alt-coins prise will change in same way. Bitcoin was first currency like that , while now there are hundreds of them.
And i think you should start trading like i did: Find any currency that you like and is cheap, then read about it often to know how it's price
might change in the future, and just sell/buy this currency to make profit, then ou can do this with more currencies, or even bitcoin(to USD)
