Botty — платформа для автоматичної торгівлі криптовалютами за допомогою торгових ботів. Ми створюємо сучасне IT-рішення, технологія якого стане наступним великим трендом у найближчі роки.
Ми відрізняємося від інших платформ тим, що нарешті робимо автоматизовану торгівлю доступною кожному. І плануємо змінити уявлення про фінанси людей на всіх континентах.

Готові шаблони налаштувань на Botty — це не «угадайка», а математично прорахований сценарій дії бота під час руху ціни активу вгору чи вниз. Ми не маємо фіксованих щомісячних підписок. Користувач платить комісію Botty лише з успішних угод.
