It is not worth investing. I think with that money, you can buy new coins who are really cheap.
care to give more detail on either of your comments?
IMHO, I think ripple is at the amount it should be. I still think it will rise a bit with things like being added to coinbase etc but I don't think the gains will be huge. At best $2 in next few months. The time to buy ripple was when it was at that $0.15-0.25 mark that it was at for ages.
When you look at some of the projects coming through like Oyster Pearl (PRL), DIMcoin (Hits exchange for the 1st time on 23rd on hitbtc) and many more I could go on with. They have a great project with plenty of room to gain with smaller total supply. PRL for example has gone up about 800% in a short time and was over 1000% before pulling back.
Ripple is safe with small gains but there's a lot of good project out that have some big gains coming.
But it's up to each individual to work out if they want to take that risk.
