Tell me about it! I started in july and went all in on ETH at ATH. Panicked, sold at a loss and lost almost half my investment. Then I got into AntShares at 5$, all in. Never looked back.
After an initial investment of around 3k, I put some more $$$ and now maybe around 5k worth of investment, I just hit 20k these last 2 weeks and it's been hovering around there.
Thing is, I got lucky. Made a lot of mistakes in the beginning and saw my 3K being reduced to 900$. I was almost crying then lol.
After you hit a good coin that makes you amazing returns (like NEO did for me) you start to get that it's possible to make money. A lot of it.
Now I just basically research and invest long term. No more panic selling for me.
