Which altcoin is best to invest in for future prospects ?

[vyombly]

I want to invest in altcoin, so please suggest me safe and also having good return coin that has a future growth.

Bitcoin is still the most likely to give you the most return for money in the long run as it is the most likely to go mainstream long term. I suggest you invest most of of your money there, than but ethereum as it is the second most likely one to be a success. If you still have money go for Nem , madesafe and nxt they seem to be decent coins, and if you still have cash go for very cheap coins and ico with some hype and sell as soon as it hits the exchanges.

it is all a risk at the end of the day I wouldn't go as far to say any altcoin is a "safe" investment. 
One I have been looking at over the last couple of months is Loyyal, it is a rebrand from Ribbitrewards and has picked up a lot of good press and offers something a little different from the standard altcoin, might be worth your time having a look https://bitcointalk.org/index.php?topic=1508111.0

Let it ride is a good option.
