if you wanna do da/shirt term trading, perhaps XMR could be good, but not good idea for beginners. After a year or so of extensive study and practice, you might win, but much mire likely you'll lose without religiously following very good advice, such as from D Man if Blockchainwhispers, and that takes a lot of work. You have to be on the ball, watching the Telegram channel. If you miss a sell signal by a few hours it could cost you dearly.

So, my advice is to do your research to study projects such as the ones i mention and D Man's signals, and if you like the use case, then buy and HODL. Play the long game, dont try to make a quick buck.
