I wonder if the storm will come ( from China ) this weekend and all coins will down .
i don't know about all the altcoins but about bitcoin, yes there is a big storm coming, the storm of people who are left behind from the rising rocket to the moon when they grow more desperate every day that price rises another $100 and feel the pain of missing out.
Should I exchange BTC to USDT and come back October ?
yes you should sell because there is a shortage of the number of coins the rest of us can get at this price level and you will be doing us a big favor.
