Millions of bot trades have already proven that automated trading works. Cryptocurrency trading bots with proven track records should be chosen from a reliable trading platform. It is also important that the platform provides you with transparent performance data, so you can create an effective trading strategy based on the information you have. When users combine a bitcoin trading bot or altcoin trading bot with a good strategy and third party signals on a crypto exchange with reasonable fees, automated trading works well.
A holding strategy is not appropriate in many market conditions. When the market recovers, a bot that sells your assets and then buys them back at a lower price will result in significant gains to your portfolio. Grid bots can grow your portfolio slowly over time rather than leaving your coins in cold storage when the market is flat.
