I have tried scalping on BTC/USD pair as one of my friend suggested it for scalping as this pair has more volume but for same level of capital with holding, I made more profits. So, you may stop recommending for scalping. It is not a way to trade cryptos.

In my experience scalping is too different from other way of trading because,
1. Scalping is suitable only in derivative exchanges and not in spot trading (shorting is not supported in spot trading).
2. You must use stop-loss otherwise you may not able to go for another scalping within a day.
3. Usually scalping traders are not into any analysis as all levels are entry/exit levels for them.
4. For profitable scalping, you must choose cheaper trading fee platform. Otherwise your fees may exceed all your profits.
5. Like you mentioned, scalping is just like rolling dice, you may get your results in seconds to minutes.
