I am not interested to use clam because this not widely accepted, very hard to use clam for me but bitcoin is more flexible to use, on JD i played long time ago when it was used only bitcoin for betting but when it converted to clamcoin dice, I am not playing there even it is very popular dice site.
Is your fear that you will not be able to buy / sell back to BTC if you convert to CLAM? I myself have executed larger BTC -> CLAM (gamble) -> BTC trades upwards of 20 BTC at a time OTC. The onsite /tip and /escrow functions allow for safe transactions without paying the exchange fee's. I was the same when I first came back to Just-Dice.. I used to ONLY gamble, but now I do a bit of both and earn a nice piece of the staking rewards to help back my CLAM investment.
Would like to hear from others on this as well!
