Thanks mr. J. and Daniel for your swift replies!
I still have two questions: when I bought SEC (now SAFEX) on the 8 & 9 of august, they costed € 0,16 which gradually grew to € 0,22.
SAFEX is worth half the price of SEC, namely € 0,10. Can you explain why this is and why SEC still updates in Blockfolio?
I thank you both (again) very kindly for your answers!
