#dusk $DUSK @Dusk So what happens if you try to buy more of something than you are allowed to hold? Until recently I would have said this is not a real situation. If you have funds and the market has supply, you buy. Any limit would be an artificial restriction bolted on by someone. Then I looked at what regulated instruments actually require, and the situation turns out to be ordinary rather than exotic. Some instruments carry caps. A single holder may not exceed a certain share. Certain categories of investor may only take a limited position. These limits exist in the legal documentation of the asset, and they are not optional for the issuer. What caught my attention is where the limit has to live. If it exists only in a policy document, someone has to check it manually after the fact and unwind anything that breached it. If it exists in the asset itself, the transfer simply does not complete, and there is nothing to unwind. That difference sounds small and is not. Prevention and remediation cost completely different amounts, and the second one usually involves lawyers. What I cannot judge is how flexible this stays when a rule changes, since the limit written today may not be the limit required next year. From here I stopped reading transfer restrictions as friction added to a token. Sometimes the restriction is the reason the instrument is legally allowed to exist at all.
