I have still doubled my investments from buying just before Christmas, But If I had cashed out in January I would have gained about x7/x8 on my original investment.

The Lessons I have learned:

1) Not holding enough Bitcoin.
2) Over invested in Alt Coins.
3) Not taking profits.

This bear market has put me off investing more money into Alt coins, it's been an eye opener on how quickly Alt coins collapse. I have no choice but to hold onto my coins and hopefully the market will recover. But ultimately Bitcoin is king and further investments will just be in Bitcoin for me with 10/20% gambles on up and coming coins.
