Thanks everyone for your replies, I've really enjoyed the various outlooks on choosing an entry point.
I didn't take the plunge on OP or IMX despite their significant downtrend, partially as I fear Bitcoin dropping to $25K and better buying opportunities may present there.
I've made the mistake of buying a few others HBAR, AGIX, AR as prices were dropping .... and then they dropped significantly further. Perhaps I should have waited until prices stabilized as suggested. Or DCA'ed in so I could potentially buy lower too.
I guess I'll keep my powder dry for now and watch for OP targets mentioned above of $1.2 to $0.9
