BTS' smart contract are more secure because they are less flexible .. there is also clear rules that bts will fork to fix bugs if the code doesnt behave as specified.
thats makes it easier to derive a risk for holding assets in bts .. essentially equivalent to holding btc
not true .
no computer program is more secure just because "it's less flexible" .
BTS1.0 had a big bug that result in huge transaction fee lost . And that's with "less flexible smart contract" .
Of course , if you're referring to it based on "programming secure" (like argument against some programming language) and not "actually secure" , then i agree.
