Earning in this situation....
If we observe BTC movement in daily chart it is evident that during last week bitcoin valve varies between 63k to 68k. so if newcomers want to trade they should follow the pattern on daily trade.
In case of xrp figure of 6.1 to 6.5 is the bracket inwhich you have to play.
If you buy higher and sell in panic then you are giving to market rather than earning from it.
for beginners it is always a good policy to play on spot crease rather than in futures..
