Bitcoin has a scalability problem, with a very limited number of transactions per second that can be processed worldwide. It can take at least 10 minutes for a Bitcoin transaction to be confirmed, which makes it unwieldy for use as an everyday currency.

Transaction fees are relatively high for small purchases and vary depending on how long you are willing to wait for confirmation (10 minutes to 1 hour).

I was an early participant, but the open ledger blockchain always bothered me, even at $30/BTC I considered my easily mined horde of 30 coin more of a liability than an asset were I to use them.  I suppose at over $1M I might now want to somehow sell out of that position even to get a better crypto but I never foresaw the stupid speculation that occured so I wiped the failing disks and flash media with my keys, oops, no $$$ for me. 
Back on topic, better cryptocurrencies that are not scamcoins, pyramid scams, anti-privacy coins, or run by a corporation for profit are out there, scaling can be fixed as can the other problems but it requires a team of devs who are principled and probably anonymous to not be easily pressured to turn against the hodlers and miners.
I was a holder yet a non-believer early on, now I just want a privacy replacement for credit cards, cash and paypal; no speculation, just money I can easily and privately spend on dinner, airline tickets, or electronic components.

A privacy friendly currency would be great.  But BTC isn't it, (securities used for massive investment are not suitable currencies)
