Hello, this cannot be explained quickly. I use https://www.cryptohopper.com/ and have the hero subscription there. I have also subscribed to a signal from someone who uses an AI to calculate the probabilities. It has paid off over the year, but two years ago I had high losses, but ultimately only because I sold. You only ever make a loss when you sell. Some of my coins have been down 50% for 200 days, but have now been sold at a profit. It is highly speculative and you always have to reckon with a total loss. Above all, the coins are on a stock exchange and if it goes bust, as has already happened to some, all the money would be gone.
