Every new site will sometime become old and trusted, just that some few ones try many shady deals while trying to survive their early stage.
I wouldn't say that every new site will eventually become old and trustworthy. That's an optimistic assumption. There's a lot of competition in the market and not every new site will survive.
You are very correct on this, I was optimistically assuming. Maybe in the absence of drawbacks my assumption stands. But the real meaning of the statement is that new companies should try to do the right things, having reputation and customer satisfaction as their key objectives. That if they continue this way, then their company would be aging and getting trusted.
So, to be correct in my above statement, I have to rephrase it thus, "every old and trusted site, was once a new and untrusted one"

Yes, when the oldest sites were starting up, they had zero trust, but they built it based on honesty and based on fundamental values that are what we look for in a platform, that the sites comply with their members, that withdrawals are given at the right time, that there are no problems to make deposits, or cheat with welcome bonuses and that they comply when a person wins a prize.
The major problem with dome new gambling companies is that they want to achieve success in the shortest time. This pressure pushes them to promise what they cannot deliver and once they failed to deliver, they will be tagged scammers. You will see a new company doing hight promos and welcome bonuses that established sites cannot do. When they fail to deliver on those promises, that will mark the beginning of their problem.
That is why some company will start genuinely but later becomes a scam. I don't think that is the issues with 1xbit. 1xbit deliberately choose the path of scam.
