My dear ,i am a leaving testimony of the reality you are trying to make other people to embrace.though ,i did not plan for long term investment on steem blockchain but it happen by chance.the time the price of SBD was $0.95 , i bought 25.4SBD hoping to sell it at the rate of $0.99 or above it but it happen that instead of it to appreciate in value then it keep on depreciating .that event made me to forget that i have some SBD in my bittrex acount. I did not know what me made to check my bittrex acount during december period .guest what i saw ,i saw 1 SBD equivalent to $18 i quickly sold it and make huge amount of profit.then i realize that steem blockchain is very good for long term investment.thanks for enlightning people more about long term investment on steem blockchain ,really ,it one of the best crypto to engage in long term investment.
