You can mine monero on minergate.com  even stealth mode

 Exchanges will have to agree on zero fee. When i have 100 mIOTA in bitfinex.com and I wish to withdraw,I receive all 100 in my wallet.
Not all exchanges like that

It is not complex if you understand it. If you wish you can generate a new seed, open note pad, CAPS LOCK in your keyboard and write a string of 81 capital letters as scrambled as possible, include 5 or 6 times the number 9 ( NMHYGRD9DFGJJ9......). all 81 characters, count them well, login with this seed and press receive to generate a new address, attach the to tangle.
The SEED is the key to open you own reserved space in the TANGLE. In this very private space you can attach endless addresses(in the near future you will have one address for every household appliance linked to the internet of things)
It is important to understand that you can use any of your attached addresses for receiving as many times as you wish, but if this address is used even once to send iotas away, than it becomes obsolete. To make sure that you are not using an address that has been used for sending, you can attach a new address every time you want to receive
 
" Non reusable addresses
IOTA's addresses should only be used once (for outgoing transfers). That means there is no limit to the number of transactions an address can receive, but as soon as you've used funds from that address to make a transaction, this address should not be used anymore. The reason for this is, by making an outgoing transaction (if you send IOTAs) a part of the private key of that specific address is revealed, and it opens the possibility that someone may bruteforce ("hack") the full private key to gain access to all funds on that address. The more outgoing transactions you make from the same address, the easier it will be to bruteforce the private key. It should be noted that having access to the private key of an address will not reveal your seed or the private key of the other addresses within your seed / "account"."

Only CPU mining can be done on laptop and i don't think that is going to be profitable

DASH seems like a closed group who controls every thing including the price.

Does this use TOR network for stealth transactions

IOTA holdings are my pension fund

Just another NXT platform
