Light mobile wallet is definitely a good solution 
I didn't have the problem, I downloaded the snap and after 15 minutes, the sync was done. after 24h, synchronization takes about 10 minutes.
The problem not so many people can download a full blockchain, maybe if someone wanna mine it and that will worth to download it. but when you are only a buyer from the exchange site and that wants to store your coin on the wallet and light wallet should be the only solution. If there will be another wallet to be used on the android or IOS platform will much better.
