We knew that Bitcoin is still the hottest performing crypto of all time, but I think it is better than you should look at the other options as well so that you will not be disappointed if one of them goes down.
While the prices are still cheap and affordable, it is like a "FUD sale" where you can buy them before it goes back up again. It's a good thing that you are going to buy, but it's definitely up to you if you go for Bitcoin or explore altcoins.
Always the hottest and will forever keep being the hottest. The thing is that except for the short term massive gains that most altcoins usually end up having, most of them still always tend to respond a lot to the movement of bitcoin which in the long run makes them get affected badly when bitcoin is having a huge bull run or when in a bear trend, but for bitcoin, the future is guaranteed and buying at a low price such as this even makes it awesome.
The market is holding up strong so far and buying within this point below $10k is a good one while waiting patiently for when the market will recover and we may start seeing a lot of progress in coming months. Also, we have to remember that the whole huge market correction was as a result of the MtGox sell off, so one way or the other, if this gets out of the way, we should see some good movement.
