Yes, it is wrong, because there are a few people here, perhaps just one with dozens upon dozens of accounts and more than 30k in SP, whom will gladly jump on the opportunity to remove a chunk of your rewards.
You will be at a position to fight him and cause him lots of damage, but the difference between you is that you paid for your 30K, whereas he paid much less for premining his over 30k, which explains why he can allow himself doing so, while for you it will be loss of value.
Another reason to why it will be wrong is because at the current prices, you will buy at bubble prices and suffer from its popping, and even more importantly, I doubt that STEEM will be worth over 0 a few years from now, because such a decentralized platform can not scale to centralized platforms dimensions, and I hope I am wrong about it.
Anyone inform me if I am.
