Thank you for more answers,

our main reason to use a coin and not a token is the usage of the coin.
We don't want to just collect for example Bitcoin, Ether etc. to then give out our coin (= ICO) but we want to continue using that coin in the platform internally.
So no, we do not just want to make an ICO to start a project.
Instead, we want to start the project AND make an ICO AND also make it possible to get some of our coin for free (bounties, airdrops and more).

We don't have much experience in both cases, but using a coin will be much more secure for the users, as they will hold their private keys, and easier for us,
as it's easier for us to program with a coin then with a token (solidity).

The project we will start, will be a smaller project and not too complex. We have watched much coins and tokens where the developers did not have professional experience but still succeeded. In the crypto world does not only the project with the most experienced staff succeed. There are way more factors than just that and we're constantly learning about those.

I simply just had for a too long time only ideas and want to start a project - not only for money, but for the experience I get out of it. This thread was to see how the users here think and I am very happy to see that so much would support still a coin, even if the tokens are so easy to get.

I don't give details about the project as this thread is just for the question of whether using a coin or a token.
For sure, at the end it will be our decision, but it's very interesting to read about how the users think.

Thank you for these nice answers!
I'm still open for ideas and wish everyone a great day!
