I've worked in the Risk department of a CEX, and all transactions were analyzed by an AML/CTF algo. On the other hand, it's a set of factors more than the transaction itself that can lead to the transaction being frozen. Each user has a Risk Score based on the frequency of deposits/withdrawals, the amounts, the origin of deposits, their country of residence, and the SoF questionnaire they filled in on registration (income, expected volumes on the platform, etc.). Clearly, coins with a history with a casino or mixer aren't a problem if they're the user's only red flag, but if other flags are present, they'll use this as a pretext to justify asking for the origin of the funds.

I also invest in both, litecoin and ADA. But honestly I prioritize Cardano ADA over Litecoin. Everyone definitely has their own considerations and analysis, and I also agree with you that we should have both because these coins have the potential to be held until next year.

Yes, I used a demo account when I first learned to trade, and before I didn't know Binance and other exchanges, one of my friends asked me to trade on one of the platforms, but it was very difficult to trade on that platform, after I got to know crypto and the first market I knew. I know Indodax (local) for global Yobits if I'm not mistaken
