I agree with this.
$1 minimum bet is way too much and just limits small players from playing. Even though they may not bring a lot of gaming revenue, they form the basis of the community at your site so it makes no sense to disincentivize them from playing.
If you have dice roulette or any luck-based game, players want to bet a small amount when starting out and they go on betting huge amounts of money when they feel they are going to get lucky, so far this casino does not have a dice game yet, but when they finally added they will need to lower the bet, so it's better to start now, for newbies and for those who want to try out their games for the first time.
