Because of the benefits for having tokens on the network, I am confident that there will be quite a number of them.
As to SAFEcoin, I am sure it will still maintain reasonable value even with all the other tokens since each has their purpose and SAFEcoin’s is to buy resources on the network. Everything else SAFEcoin will have to compete with the others. One advantage of SAFEcoin will be the network is specifically securing it and up to now has been said it will be without fees (no PUT charges). As to whether it remains so, well there is a good case for it to remain so, but there are potential issues calling for it to also require some minor charge (eg a PUT charge). There will be a receipt charge always. A receipt is optional and is where a copy of the coin is made as a receipt at the time of the transfer.
Tokens will have the fees whenever there is an operation on them requiring a PUT (eg owner change, value change etc)
