I bought more Litecoin at $61 a few weeks ago, then watched its price rise to the low 80s.
Then everyone started shitting themselves over this Corona Virus bullshit, so the price retreated to $60 again. If I'd been able to predict the future I'd have sold at $80 and bought back in at $60, but I didn't.
So I lost some profits. Farq.
I do not think there is anything like opportunity missed in crypto currency, because crypto currency is a field where there will always be an opportunity.
What to do is to position yourself in the proper spaces, so that you can get in and join the next available opportunity.
Thats why you need to have a comprehensive trade guideline, to guide your decisions.
