| Как я перестал верить в universa. | |
| Я Артур Липатов, комьюнити директор Universa.io и это моя история, не уверен что он понравится в ,,Uni,, или как я стал топить за юниверсу в международном комьюнити.... | |
| В ноябре 2017 я познакомился с Александром Бородичем, с первых минут общения я понял что он очень достойный человек, и мне интересно с ним двигать технологии вперёд. Саша предложил роль комьюнити директора. Псевдо NDA, в котором я поднимаю капитализацию юни до полумиллиарда и получаю комиссию в 10.000.000$ сегодня перестал иметь ценность и тут я понял что все СТОП. |
