I want to lease some waves which I bought it for long term point of you. So instead of keeping in my account, I would like to lease it out and earn some extra waves.

Please confirm is it the correct address to lease it - 3P4MRJvttkghWsXxGZ61kqd2M79GtLujoey ?

After some time if I want to come out from this lease agreement what do I need to do?

I bought few altcoins since last week and as of now still keeping my all altcoin in https://bittrex.com/ site. I know it is not good to keep it there for a long time.

I have below altcoin now and need you guys advice on which are the good online and offline wallets for these coins

1. ETH
2. NEM
3. DOGE
4. Waves
5. LTC
6. Ripple

Your help will be greatly appreciated. I'm new to these coins so nee your best advice

Thank You
