I understand why you frustated,because bitcoin lost its big value ,but see one thing bitcoin market has growed and has strong farmers and solo miners into it ,sharing the healt between them.If bitcoin achieves mainstream on the next years you will change your opinion.Bitcoin todays isnt a shceme to get rich fast ,bitcoin allows anyone to make a good income monthly .I dont bother if bitcoin is 200 or 600dollars ,bitcoin is an extra,and sure it makes a difference that i can spend one day to buy something i wanna ,till that i believe bitcoin is the future.
Totally agree with you, bitcoin is very soon goingto be in mainstream. like some time before when online shops were started everyone told it wont work but now see most of the business are done in online shopping, so everything is becoming now online, and bitcoin is very soon going to be associated with them then obviously everyone is going to buy bitcoins.
