$50 is really too less to investing but you can choose coin which is under $1 and hope it will go to the moon in the future. I recommend Siacoin which its price is 106 satoshi and i think it can go up to 5000 satoshi in year 2018. You can also choose Dogecoin which is 35 satoshi, Dogecoin is less potential than Siacoin but it is also  a good coin

Right now we are seeing a pump and dump move toward bcash, thus trust in bitcoin would fall, and bcash would crash, so the only other safeheaven for me is ethereum.

A mate told me that Cindicator has the potential to become the next bitcoin in the future. Then I look to see if it really was a good coin, and I think he's a bit right. And 50 dollars can buy a lot of that coin because it's price is not so much expensive. I'll soon try to invest on that coin when I got my payment because I think it has the potential than the most, so you can join me at my ride if you want! Just only if you want!  

Yes $50 is a very small amount to invest if dogecoin it is too long to gain profit. It is cheap but long term is good for investment in this coin. For me I will invest in ethereum it is profitable so also good for long term.

very difficult with a limited amount
but you do not have to worry, you can invest in cheap altcoin. but with one load, you have to learn first. and hold it for 4 - 5 years

Probably in coins worth 2$ or less then sell when they rise a bit. Short term

I would invest in new project that is growing and developing. I personally, having not a large amount of money, joined the Bitcoin White project and i will buy their coins when they appear on the exchange 7 january.

You can actually start with it. I would say ripple had it been it was early this year but now you can't invest in that. With $50 i will advice you to invest in a shitcoin i meant a coin with large circulating supply. If it increases one day you will make uge profit from it.

50$ is no much of money for investment, but there is a chance to make a profit of it though. If to buy ICO tokens for instance and hold it for a while till the moment it grows higher.

i will buy coin with aggressive fluctuation but still have good prospect...and never cutloss
