Sending both your SV and ABC coins is making a future bet that one of the two chains will not be important enough to continue, will not have enough support to continue, or perhaps will be attacked enough by a 51% attack, and mining enough empty blocks that people will eventually leave that chain. I think however given the amount of support, and hash rate between both of the chains all of these are very unlikely scenarios, as seen here (

. As mentioned above, each chain will not see transactions that are incompatible with the other chain, so all you have to do is send your bitcoin cash from your main wallet to a new SV address wallet with a SV op_code (such as op_mull) and then make a second transaction from your main wallet to a new ABC address wallet with an ABC op_code (such as op_dsv). This way you will split your bitcoin cash, and make each
