Prepare a reserve fund to anticipate these losses, so that later there will be funds to get a return on investment. The reserve fund is very necessary to meet unexpected needs or risks. It takes patience and endurance, because with what we know a currency will rise later, especially the currency that we predict will profit and it is possible to decline according to the conditions.
Or just invest what you can afford to lose and hodl? I mean,,, reserve funds and anticipation are great but we all know we are at best amateur traders and investors. If you believe in the network, then you know long term is the only thing that matters.
Altcoin investments? Who has time for that?
