The best way is just that ... make a copy of your .wallet file in a secure place, that way any problem in future and you will be "saved"

There are plenty of other exchanges that are much cheaper for a listing, and better reputations.

The real issue would be to find a good exchange, that is supportive of cryptonote bases coins.

Given one is found, The devs should start up a donation pool, or buy into it. Intense has been listing on 1 exchange for a long time now. It needs a bit of diversifying.

In my opinion they should incrase main pool % to get value to submit other exchanges ... No?

But wait, 15% premine which is 150 million ITNS.
Why would not a part of that be enough to get listed on more exchanges?
Even if I think developers should be rewarded this is a huge amount.
Why not just sell a small part to these kind of things?

It is NECESSARY to show her in Blockfolio it important for investors

10% is for the core team and 5% is for bounties and reserves.
For the time being developement is more important than getting listed on new exchanges.... IMHO that is.
If the devs actually see the possiblity making a good move for ITNS in investing there own personal funds for listing they would probably do so.
But who knows how many of their funds are still in their hands and not already spent

I think is ok - and comparable small with other coins - that now we have 1/3 total supply already. 

Im sure they need them to other much more important things related with Intensecoin project.
So in my opinion that isn't a solution atm.

If you do it well you will not have problems. You can search for it in YouTube. Maybe you can get a good configuration to OC your GTX 1070

Hello Sir.  Can I ask which of these VPN protocols will be used by Intense?

  Layer 2 Tunneling Protocol (L2TP),  L2F,  Point-to-Point Tunneling Protocol (PPTP),  IP Security Protocol (IPsec).

Or are you creating a new protocol?

Thnx.
