Is it even worth investing into Bitcoin?

Do not invest money more than you can afford loose. A month ago when the stock market crashed, bitcoin's value shrank to USD7700, but now it recovered. It is almost USD9500. If you had bought after the crash, you could gain a lot.
There are some market speculation on some alt coins' rise of value. Etherum and Bitcoin Cash are among those. But do your research. Study trends of the economy.
