Investing can be a great way to earn some extra money. If I were you, I would also buy more btcs and hold them for some time, since there is a good reward-risk ratio investing into it.
That is right. The bitcoin is a good investment tool. The other coins are the Ethereum or the Monero or Nxt.
those altcoin is just for alternative it can also good to hold if you have that altcoin even a small amount ..
For me i am investing in bitcoin and set my own margin in bitcoin just like right now the price is decreases and made already a profit when the price is increase now my buying walls will trigger soon if the price of bitcoin will continues to decrease. i have my own margin that i am sure that you can make a good profit..
