Usually the demand will boost the the altcoins value so popularity will be the nearest of it but any altcoin will not be popular if their project is shit project. So I can say that both of them are very needed to boost the value of any altcoin because if one is lacking then the altcoin value will not increase.

Marketing is another factor also which is the most important thing to any project in order to obtain their popularity and raise the demand of their coins/altcoins. With regards to Bispex exchange I haven't experienced using it and I didn't know about their insurance funding but what I saw upon checking their background, they are listed already at coinmarketcap (rank #2057, marketcap is still unknown) and it's price is dropping base on their chart.
