Buying at the short term peak doesn't make it a bad investment. Not trying to sound too critical. SP is designed to hedge against 90% of inflation..so as I understand it if market cap stays the same you'd lose 10% in a year on SP. Steem Dollars are set to gain 10% per year regardless of Steem pricing. I made a much less popular post suggesting that if total amount of Steem Dollars ever exceeded Steem market cap, holders of Steem Dollars would lose their money. I am still not 100% sure that's accurate but I believe it is. Despite that I like my odds here. Sorry it hasn't worked for you (at least not yet)
