As an "investor" (really gambler) you look at the token first and the usecases.
Tomo might be a successful investment based primary off the fact that Tomochain cannot run without the Tomo coin unlike other projects, it's not just for mining rewards, since it's POSV you literally need to hold the tokens just to become a masternode, and you need the tokens to vote people in so they can secure the masternode. Right off the back Tomocoin has made itself two very important usecases, then comes the paying for fees like every other coin which is it's third usecase. Then the DAPPS built on it will most likely add it as a payment option which is a 4th, + just being a payment option in general which is a 5th. From a "investor" or gambler stand point Tomo gives you usecases as well as a Stake in the tomo's blockchain itself since your vote quite literally picks who secures the chain and the better they secure it the more rewards you get., which you are rewarded with. With Tomo you can honestly say you're "invested" blockchain. This is exactly why we're about four months into the mainnet being released and why there's only one DAPP (Tomodice) and "Investors" have willingly locked up more than 50% of the circulating supply. There is a demand for this token at the core. TL:DR the token isn't useless and you actually need it to run the chain.
From a Developer stand point: Tomo has around 2,000 tps which was already tested with that spam attack we had the first few weeks in, People are all in a race for the TPS but even 2,000 TPS is overkill at the moment. The tomo team is open to work and promote new projects built on it as well as making it as easy as possible from switching over from ETH. Things like Tomox will make one order book for all tokens built ontop of Tomo meaning your coin will have true equal liquidity across exchanges when Tomox comes out and there will always be somewhere to trade it. TL:DR The project itself is strong not even mentioning the partnerships.
They say 90% of the tokens will go to zero, and this may be true, but Tomo isn't one of them. Since the ICO craze people keep treating this market like it's the stock market, they look at the partnerships a project has as well as what the project is doing itself. They don't go and look at the token when that's the most important thing since they don't have stake in the company. 90% of the tokens are payment options for 1 service since majority of them don't even have their own chain, the projects can run without the token and being a token holder gives you no rights or rewards. This doesn't even cover the fact that a lot of them have billions of tokens in circulation. AFTER you are sure that the token at least covers 1 of these 3 (You cant run a node unless you have 50k tomo), the coin gives you some sort of rights (You literally vote who secures the chain) and it gives you a reward for doing so (The reward for staking). Then you should move onto the project itself and cover why it's strong, looking at the partnerships and so fourth, which is why I covered the tokens usecases then the project itself.
