Some people are saying bitcoins and ethereum block chain will become too bloated as users increase making it extremely slow to sync and use, will Nem face the same problem as it increases in popularity our does Nem Have different solution to this problem?

How many transaction per second can Nem handle at this moment and can it handle a million users right now? I am sorry for asking too many questions.  It's been a long time since I followed NEM so am trying to get up to date.
