If you could give us some more information like what price you bought those coins at and till what time do you consider holding onto them, we could help you out. A nice chunk of coins you have invested in have been rising up until recently.
Yeah that's the problem, I just started investing 2 months and many I bought were at peak and then went down. for example bought xrp 0.34 now 0.25, bancor 4.5 now 2.50, agoras 80 now 50. but blackcoin bought at 0.23 so that's good. doge reddcoin and siacoin are also fine, just haven't invested in those as much as I did with xrp bancor and agoras lol. I am planning to hold as long as I think is enough, for example if ripple went to 2 euros I would sell for example, or maybe keep. bancor at 10 or 20, but if that means I have to hold 5 years that is fine for me. I don't have a time which I should keep
I think that is a good plan. Don't sell at a loss, unless you lose all hope in a coin. Also consider selling just enough coins to cover the investment cost and then keep the rest and see what happens.
