Swing trading is probably the best method and the other one is simply buying the beart market. All cryptos offer a very nice opportunity in every big bear market and this one wasn't an exception. I bet that if you bought at any time between January and March of this year you'd have more money than you have from scalping.
That's certain idea mate, any trading strategy can be effective depending on the asset that we have. Any method can be applied as long as you're capable in handling with the funds that you had, because once you cannot sustain I think panic will start to occur. Bear market isn't a bad thing that happened in crypto, we should embrace it and take that opportunity as a biggest chance to do trading at your own freedom as well. Use your money wisely, buy promising coins during the dip and sell at high, and trade using long term strategy.
