I read your page and WP and If I understand this correctly. For example- the platform will buy me BTC for $10 000 on exchange A and in same time sell my BTC(which I must already have there)for $10 100 on another exchange?
This is quite clumsy.
Think of it like this, for btcusd chart in exchanges A and B. You have 10k USD in A and 1 BTC in B. ARCT uses your 10k USD in A to buy 1 btc for you and then sells your BTC in B for 10,100 USD. So you are now left with 1 BTC and 10,100 USD which is profit compared to what you started with (1btc and 10k usd)
