personally i think no, but only time will tell

It's definitely a good news that Uber accepts Bitcoin. 
I believe it will be another big step for cryptocurrency.
The only problem is Uber is losing in China so i cannot take this best deal .. LOL

Maybe Bitcoin will die some day but at least not at this moment or soon. The price of bitcoin is still skyrocketing and i still believe cryptocurrency has the most potential. 

The site seems good. I can try. What's your plan then?

3 weeks ago, Bitcoin's price was no more than $3000 and it just jumped to a record $4500 yesterday.  I believe it will go up still so you can put some money in, but do not put all your eggs in one basket. Good luck!:)
