It's about 83% back, not 55%.
61.79% is in crypto coins. 38.21% is tokens. Tokens are about 0.55 of worth.
So, 0.55 * 38.21% + 61.79% = 82.81% of the funds has returned.
Tokens are sold at 0.55:ish now because people are willing to get 55% of their fund out now instead of waiting and get 100%. If you don't sell your tokens you will get 100% of their value back (assuming the site doesn't go belly up before then).
So if you're willing to wait, you'll be at 100%.
