This article was published last year when Bitcoin network are experiencing congestion with unconfirmed transactions (spam transactions), but have you tried sending Bitcoin this past few weeks or month? I can even send a Bitcoin right now and pay less than $1 and gets confirmed faster than before, it might not be the fastest cryptocurrency to transact but it is still faster than sending money overseas. What do you mean that Bitcoin is not secure anymore? is there any instances that the network gets hacked? lol. and owning a Bitcoin will not give you completely anonymous from the very start.
