Emotions do play a role in our decision making. Many in this space know about HODLing but when it comes to practicality in such an intense situation, most of them with weak hearts tend to lose. Only experience could teach until we are willing to learn. Though this dip was extreme, it was going to happen. That's how crypto work. Faith and Patience pays off. It's not quick and easy money, it will test your grit to an extent where you could either break or survive to prosper.
CoinBase implementation of SEGWIT will bring BTC/LTC to mainstream adoption this year. Lightning Network is already working on mainnet for offchain scaling.
This year is gonna be interesting. Many are going to miss the chance they had. It's not the value of the crypto but the innovation is definitely going to pay off.
