There are periods of time when it becomes very expensive to send small amounts of Bitcoin. It does impose a kind of 'mandatory HODL time period' for small-scale Bitcoiners.
I agree that with Bitcoin, a longer holding time, a better chance for a holder to get more profit but I really dislike situation when we have to hold our bitcoins while we don't want to hold it with a funny reason behind. We have no other choices because of very expensive transaction fee.
It is not a good advertisement for Bitcoin because we have keys (private keys), we have coins and we have need to move our bitcoins whenever we want. Can not do it because of expensive transaction fee, is a big barrier to bring more new people to Bitcoin community. It's big fear that you have bitcoin but can not do it, because if you do it, when transaction fee is unrealistic expensive, you will convert your bitcoins to satoshi dust.
