A couple days ago I transfered enough from my bank account to buy 1 Bit coin. While waiting for the $ to make it from the bank to the exchange I had $75.00 invested so could use it to practice with. Keep in mind that I had no experience with bit coin trading and my past day trading did not go well.
Today I saw that SC (Siacoin) was above 10% and volume was above 10,000. It was also very active pumping up and down. I did four buy and sell trades, not aiming for much more than 5% profit on each one and increased my $75.00 to $91.00. It was a great leaning experience. Also very humbling because on the first trade I made a mistake and lucked out.

That's a good way to start. Be careful not to panic buy or panic sell and you should do fine.
This is probably one of the reasons why newbies should read recommendations on here that people start trading on a small amount before putting real money.
