Recently I've found a free but handy tool -- a Cryptocurrency Alerting service.

You create an alert filter and the service sends you a message when the filter is triggered. The alert filters are cryptocurrency-related, obviously.

What is so good about this service?

1st, it's free. Or more exactly, the free plan includes 3 alert filters and a handful of options, quite enough for those who trade "in-between jerking off" as one smart guy once said.

2nd, even the free plan has a good selection of trading pairs and exchanges. E.g. I can monitor BAT/USDT at Binance and BTMX/USDT pairs at Bitmax (not Bitmex!) exchange -- something I couldn't find on other free alerting services.

3rd, even the free plan has a good number of alert methods. It supports email, Telegram, browser notifications, Slack and Discord. There're also phone and SMS alerts but they're available in the US only, as far as I can understand.

Shortly, Cryptocurrency Alerting is a good thing, especially considering its US$0.0 price.
