A good crypto wallet should be able to perform a Normal send and received functions fast and without any personal details requirements. It should be able to also ensure and guarantee the security of your assets and be backed by strong regulations. Always look out for their transaction charges and fees and see if it suits you.
NXT free wallet seems to be a product of the nxt block chain. But claims are that the wallet was launched in 2013 by some anonymous group but it has been performing outstandingly over the years. The wallet has a very easy to navigate user interface. I enjoy navigation. It has listed a good number of coins which you can save or hodl in your wallet. This includes my favourite coins BTC, LTC, doge USD, and more. The wallet has receive a good report though withdrawal fees are a bit high and significant. It is still a recommendable wallet in my opinion. So if it suits you search it in your play store and go for it
