Yes, bitcoin already recovered from the fall of its price last month and I look forward for another jump in its value in the next months before this year ends and I hope it would again reach 5000$.

It certainly can, bitcoin earnings is considerably great in those poor countries that they can use it for their living. The better purpose is that they can have knowledge on bitcoin on how to use it as an investment and create greater amount of profit.

I have noticed the greater rate of increase in the past two weeks. I always trusted bitcoin that it can recover fast from any fall of its price. What do you think? It is good to invest today? And what are your expectations about its price before the year ends?

Offline wallet is safer. It is also easier to manage and very flexible like you can change the receiving address anytime. I would recommend using electrum wallet, it is compatible with multiple operating systems and the best security.
