Ark and Lisk are two very good buys going into the end of the year. Good development teams showing real work and progress - check them out for yourselves and see :>
Ark is a good project but it has already pumped, the only route that I see Ark going in the near future is down, that does not mean that is going to stay there but I do not think it is a good moment to buy Ark, if you like the project then wait a little and you are going to be able to get it for a cheaper price.
Waiting is a wise decision and not easy for everybody who holds the coin, exact patience will be needed to develop. The demand might take for long days or even months to fulfill it's profitable price in the market. That's it's good to hold it for so long and you'll never regret ot by the time you can gain profit at exact time to sell your coins that you've been holding for so long.
