it's always interesting to have a look to that site, but consider the results carefully, sometimes the profit for one coin will spikes but it's not real, so it's to be considered as a hint, but to be doubled checked

https://stocks.exchange/trade/ONEX/BTCsell is at 0.00001048 and buy at 0.00000239 per onex, almost a 5 ratio, so the expected profit is uncertain
