| Collection of Tokens | A lot broader, together with many new or area of interest tokens | Centered on vetted and established tokens |
| Pace of Transactions | Could be slower on account of blockchain congestion | Typically sooner as trades occur off-chain |
| Safety | Safer in concept, no central level of failure | Depending on the change’s safety measures |
