Bitconnect lending experience

Bitconnect is a controversial crypto lending site to get high interest. I just want to experience it myself and have registered and lent them $410 for a locked period of 299 days. After 5 days, I got $13.16 interest or say 13.16/410=3.2%.

If everything remains unchanged during the 299 days, I will finally get 410+(13.6*299/5)= 1196.

However if I re-invest my interest every 5 days into the principal, the compound interest calculation will be as follows:
Total value
= P(1+r%)^n
=410(1+3.2%)^(299/5)
=2697

After the calculation, I decide to use the latter method to see how it results in future.

However I always bear in mind that I just put something I can lose in view of the following risks:

1. Interest rate may change from day to day.
2. Maybe one day it turns out to be a scam before the locked 299days.
3. The whole crypto world collapse.
4. Hacker attack.
