Does robo platforms purchase high risk assets like crypto as well?

Currently, the robo advisors in Singapore do not offer crypto in their portfolio offerings. Most robo advisors claim to deploy algorithms that would perform re-balancing based on a pre-defined risk level, and would trigger upon such data (example from Syfe). Net returns for robo-advisors should be usually higher than unit trusts due to the lower charges and expenses, as ETFs are usually used in the portfolio (with the exception of Endowus, who uses low-cost unit trusts).
