Yes, you can trade in bitcoins. Not only bitcoin but all cryptocurrencies. Right now i am just telling about Bitcoin. Before telling how to trade, let me first clear your doubt about legality. Trading in bitcoins is very much legal. In fact it is being traded on New York Stock Exchange. They have a separate Bitcoin index NYXBT. This clearly shows legality about trading in bitcoins.
Now coming to first part how to trade. Obviously you need an exchange to buy and sell bitcoins. Most countries now have Bitcoin exchange. For ex Coinbase is famous Bitcoin exchange in US, Bitstamp in Europe, Zebpay and Unocoin in India etc.
There are over a 100 stores including familiar Subway that accept bitcoin as a payment. There are already IRS laws where in it is treated as income. Any profit that you make trading cryptos is taxable per normal Short term/long term capital gains.
When SHTF, bitcoin is going to become the currency pretty soon, like in Venezuela these days.
