hi My friend noticed that in the last few weeks both the price of bitcoin and altcoin bled, is there anyone who can give me good advice for buying and trading that is good and safe. because I heard a few months ago that the Binance exchange was at the restat, now is it safe if I return to trade there, because I have also traded a long time in binance, so I was on vacation to trade there, because at that time Binance was at the restat. Thank you and I appreciate all the answers.
