People say litecoin will become $1700 by the end of this year...
If it isn't what other coin would you recommend me to invest in?
BitConnect? IOTA?
the two coins look promising...
The fact you even thought of "investing" into BitConnect shows you have absolutely not done any research. Before asking for consultation here, you should always try to make yourself an own opinion. What if some fool adviced you to buy his next cool shitcoin? Always do research.
