You can activly buy and sell Bitcoin at Bitcoin exchanges, buy low and sell high is the key. You must know that it's High risk, but sometimes high rewards, i prefer with long term investment with big capital
Goodluck

I agree on the long term investment. The thing with Bitcoin is that you might lose money in a short term but it is very unlikely that you will lose in the long run. Even people who were buying at $1,200 in January 2014 will not lose their money if they hold their coins two years more (from now), but if they bouht at over $1k and then sold at $500 four months later then of course they lose.

Doing trading is an art. But to start successful trading it needs proper home work and knowledge about market.

While doing altcoin trading trader must have to keep watch on graph of certain time duration along with total volume, buy wall , sell wall and order book. Which can help to do better trading to receive good ROI.
