The site itself isn't the issue (I trust Dooglus immensely). It's CLAM. You need to keep in mind that BTC itself is risky. When you then move to an alt, you have an extra layer of risk (if BTC crashes, CLAM does. If CLAM crashes, BTC won't). So your risks are then:

1) The site
2) BTC
3) CLAM

Invest accordingly.
