The rules of great succuess in crypto:

• Step 1: look for coins that you like and see great potential (steem)
• Step 2: invest
• Step 3: erase blockfolio or bitcoin ticker from your mobile
• Step 4: chill and have a good time with friends, family and even your wife
• Step 5: profit after several month!

If you don't follow those steps you probably lose your money. Furthermore you will have a very stressful life, no sleep and end up hate yourself for your mistakes.

And learn this lesson: you can't control the situation. You can't change a 30% bitcoin gain or decrease. You can't forsee what happens. And you can't fucking beat the market.

But one thing is for sure: if you picked a good coin it will eventually recover with even more force. The only bad thing that might happen is if cryptocurrencies get prohibited worldwide! In that case you should cash out asap...
