investing in the ecosystem is probably better than just hoarding HP and setting up auto curation, at least you're supporting people who are doing some business with hive.
Swap-Hive is just used as a bridge to buy other tokens and even buying it does support core devs behind hive-engine, bee token, etc as there are small fees. If you're using Swap-Hive to exit buy buying Eth/BTC/Steem/whatever then no, it's the same thing as dumping Hive.
