Im investing small ammounts of bitcoin into some altcoins that i believe are under the real value, soo i will hold them till end the year atleast and then i will think what i will do if sell or wait a bit more, usually the savings returns good profits and almost without risk.
You never know what to expect. It's the worst thing here. And investing in altcoins small sums (I guess a few cents/bucks) has small profits too. And if you invest in 5, for example, 2 of them can rise and 3 can fall in price. And you can go in negative profit.
I wish you best of luck, but I don't think investing small amounts would bring you mich profit.
The development of the bitcoin has slowed done recently. That is the reason of the bitcoin price drop. People are investing in good altcoins.
