This probably means you're invested with amounts you're not comfortable losing. I would've understood more if you were checking the wallet just to make sure the funds are safe...(and even then, a hardware wallet should've fixed that for you) but the price? not really. Just use CMC or some portfolio app to alert you when the price increases or decreases with a certain percentage, and forget about it.
This one!
This is the most accurate answer to this on which at the time that you have invested into the amount that you cant be able to afford to lose then you would definitely be that checking out your balance every now and then on which this isnt necessary specially if you are that trying to hold for long term then there's no point on checking it out too actively because if you are that fond of checking out the markets and seeing your portfolio is going down then there's that high chance that you will be that touching up those holdings and selling it out at the moment that the price drops or simply panic selling because you are afraid to lose or thinking that it would go to zero. Usually newbies are the ones who do have such behavior in regarding into their holdings. For security purposes about checking it out if their coins is still there then you wont be needing up to worry as long you do know that your keys or phrases isnt known by someone or havent seen then it should be just that fine.
Therefore, the best solution to this one is to avoid on seeing the market and any other crypto related sites and just focus on trying out accumulate as much as you could because this is just that intended for long term holds. You will be that disrupting your mind if you do keep yourself being updated on whats the current price and just mentioned that only invest into the amount that you can afford to lose or you are confident about it and doesnt compromise your finances on which this will be that having that confidence and worry free on this case in comparison when you are investing heavily or when you are making up that all in kind of investing on which it will be that making you highly reactive just because you cant be able to afford to lose. Simply ignore those price movements because it is a volatile market after all.
