Is the system under attack again or it is happening because of the miners? Even if a small portion of those transactions dont get confirmed, bitcoin will be dead for good. I hope devs got a solution for that kind of an attack.
What are you talking about? That is false. If your transaction ends up *stuck*, you do not lose Bitcoin nor does anything bad happen. Eventually the network drops it and you can create a transaction with a bigger fee (you could attempt RBF via Electrum right away, but I do not know which miners support that).
