The safest choice I would say. No risk involve. Just patience and faith that the price will keep on increasing. Based on the price of bitcoin and ethereum today, your profits should be just pouring down on you. I personally prefer this than risking it in day trading. Of course you can definitely earn more profit in day trading but I don't like taking that much risk. I also don't like worrying about my trades. I just want to lay down on my favorite chair, hodl my btc and eth and watch the prices reach to the moon.
