Bad idea. I'm 99.99% sure no one will sell you any good calls, people will never share real ways to make money, and often sell all kinds of junk on which you can't earn anything. So it is better to study yourself than to pay someone money for nothing, on which you can only lose money. Your scheme involves double risk. First, you risk losing money for signals which are pacifier, and then you risk losing money on trading.

If using bollinga band and the lower line is reached with red candle stick, with relative strength index of 30%, that indicates oversold market already, someone can buy, but that does not mean when it hits 30% RSI, it can hit 40% RSI and the market can go up back, it can go below 30%, like going 20% before the market can start going on back, the more it goes below, the better time to buy. Also that is how is it for overbought market when the green candle stick hit the upper line of the band, it means overbought market, if the RSI is at around 70%, 80% or higher, it is better to sell at the time.

But use the money you can afford to lose because you can buy in oversold market and the price still go down further, you can also short (sell) in overbought market and the market price continue to increase, these happen especially during high volatile market. Trade with the amount you can afford to lose and use very low leverage, I prefer 1x margin ratio.

eth for 300 usd very possible in few months, bear market is very painful, 99% of you trolls have never gone through one, I have gone through 4 since 2010.
