Unlimited Money (Exploit)
This exploit allows you to earn around 1000 crowns per minute. Take the following steps:

Find the merchant at Hierarch Square in Novigrad and purchase all of his Shells and Sea Shells. Talk to him again after you have depleted his stock and you will find that he has more to sell. Keep buying as many as you can afford and carry.
Take the shells with you and visit the armorer, who is located next to the merchant. Dismantle your Shells to receive Pearls.
Sell the Pearls to the armorer until he runs out of money.
Meditate for 5 days. The armorer should have 1000 coins again. Sell him more Pearls.
Repeat the process as often as you like.
You can dismantle a Shell at the cost of 8 coins for each effort. The Pearl you receive can then be sold for 109 coins. Naturally, this only works during the daytime hours, as merchants aren't around at night.

Familiar Tattoo
If you import your save from The Witcher 2: Assassins of Kings, you may find that Geralt has a tattoo. In The Witcher 2, he receives that tattoo during the course of completing the "Hung Over" mission. When he wakes up the next morning with a tattoo, the player can either remove it or leave it where it was. If you import a save file after leaving the tattoo in place, look for the tattoo as Geralt is soaking in his bath near the start of The Witcher 3: High Hunt.

The Witcher 3: Wild Hunt Beginner Tips
As you begin your adventure, you can keep a few things in mind to make sure that things go smoothly.

Complete the tutorials. They will acquaint you with the game's combat system, which has changed since the previous game. There's no better time to adapt to the differences.
Venture off the beaten path and explore. If you stick to the roads, you're likely to miss out on opportunities to strengthen your character, which will mean the required quests are more difficult and perhaps frustrating than they should be.
Side quests are worth doing. You can gain loot and easy experience points, especially when completing the basic quests available in White Orchard.
Make sure that you equip and make use of powerful signs in combat, which can keep you from taking damage you might otherwise.
Learn new potions at every opportunity and refill them often. You can do so by meditating, provided you have Alcohol or Dwarven Spirit items in your inventory. Potions will make your journey much simpler.
