I think, it is absolutely litecoin. Litecoin has been surviving since the starting of the cryptocurrencies and been in top 5 at marketcap for many days. Litecoin having an average price in all time with having a stable position in the market is a good choice such as BTC. These are just my assumptions.
Agree with you. One more option is DASH, because it is accepted in many stores in Asia, plus it is stable network with fast speed of transactions. I have heard that in Europe this currency is not so popular, but we know that it is only the beginning of the crypto journey.
