So everything will really be that in according into your capability and capacity on which this will differ into each person. So it will be that up to you on how to deal up with things accordingly.
Well to me it seems very difficult to trade alts, because with alts, for everything to go well, I think that the movement of bitcoin must be analyzed very well and once it is determined, then there is nothing to do but based on what can be predicted, then an appropriate decision is made. Sometimes it is not worth trading alts if it is seen that it is very likely that btc will go down, because if that happens, then the alts do it too and very quickly and sometimes without stopping, that for me is complicated, that is why the people who trade with alts and do it well and earn big, well, I admire them.
