you can.
native keys still work after segwit activates. otherwise 16mill coins are locked and unspendable!!
Wrong. The DOS attack vector is not present at 1 MB, and you can't create a 2 MB block with native keys when Segwit is activated.
lauda please
native keys would fill the 1mb base block so that segwit cant get a chance.. thus there wont be a 2mb block..
EG
imagine there were 4500 users. so far they argue over blocksize that can only fit ~2250
even if 4499 users moved to sgwit.
1 users can make 2249 NATIVE transactions. meaning only 1 segwit transaction gets in the base. so the 'blocksize. only becomes 1.000444
in short
even if 99.9% of users moved over to segwit, they are still subject to normal bloat from a malicious bloater filling the base block. which takes up the base block space to not allow segwit key users in. thus the ratio of segwit in base:witness is super low... thus total blocksize remains super low, but the base block is super filled with native bloat
