I've known bitcoin since 2012, but I'm not interested, just looking at the virtual side. April 2013, a friend invited me to play a farm game with a bitcoin prize. it was the first time I decided to learn bitcoin, I never really invested in bitcoin. I got everything for free from the faucet, advertising, bounty, etc. I have been investing with a capital of $ 10k, but I also got the money from the bounty. during 2013-2014 I played a total game of 0.9BTC and I only sold part of it in 2015, then I invested to buy other coins, Doge, LTC, ETH, DASH, etc. in 2017 all of my coins soared, flying to the moon.
It seems you did everything right, you entered in the market when it was still relatively new and you invested a good amount of money and then you invested in icos when icos were good and most of the developers were honest people really looking to advance the market not like icos today that only care about getting profits for themselves, my only recommendation is to keep doing the right thing, if you were smart then you probably have enough bitcoins to change your life.
But if you wait for the next bull run and you sell close to the top you could have enough money to never have to work again in your life and that could still be only the beginning since I see bitcoin being around for a very long time.
