the key point of holders is patience.
Not getting stressed over market fluctuation is what you need, you need to check the value every week or even every month or two.
Get some BTC and forget about it, always keeping in mind to invest what you can afford to lose and you are good to go.
Checking the market value couple of times per day is very stressing and useless unless you are a daily trader.
You got a point there my friend, don't hold if you can't risk some of your money, holding btc help you earn. If you can't handle it's risk then don't hold long term just wait till the price goes up a little from the money you just put into bitcoin. If you're stress then that means you're not ready to take risk of losing profit from the money you just bought into bitcoin. Being stress is normal for taking risk but you have to face it in order for you to get comfortable in your holding of bitcoin for future earnings. If your holding is long term then you need patience because patience ia a virtue.
