Scalping is a good idea, but future is too risky.
I'm not against future, but not everyone is capable to do future trade. Only those people who are familiar with future trade can deal with that high risk. For people who never know it, better to consider another type of trading.

For scalping, it is quite safe to do, especially during this bearish market. As long as don't set a too high profit, scalping seems effective to use. Make sure to set entry and exit at a realistic rate/price.
