Twitter user @ProofofResearch's chainanalysis claims that Canadian cryptocurrency exchange QuadrigaCX has no cold wallet storage and has in fact been using a highly inefficient and unorthodox hot wallet management system to mimic solvency.

Further analysis reveals customer deposits were often needed to meet withdrawal demands. QuadrigaCX filed for credit protection last week.
