You need to have 15,000 but should have 15,000 plus 1 extra so you can cover the .001meme tx fees to send your 15000 memes to the collateral address for the masternode.
Not necessary, it's possible to send exactly 15000 coins from an exchange with 1 transaction, that results in the output needed for the masternode
ahhhhh ok.. Tho dont the exchanges have a tiny tx fee to send?? its been while scene I had to set up any toads or send to or from any exchanges.
