“You have done an amazing job of transforming a fledgling start-up organization into a professional operation that is of real value not only to its members but to the entire blockchain space. And you have done it with your characteristic thoughtfulness, perseverance, and good humor.”
“Thanks for your tremendous contribution. You will be sorely missed, and things will not be the same without you.”
“You have professionalised the organisation, putting it on a firm foundation, provided focus, and ensured delivery. Without you, INATBA might not have made it, and would certainly not be where it is today.”
