I don't know if there is similar post, I don't find appropriate thread. However I will share my experience for newbie whoever want to HODL any crypto currency.
I have learned from my mistake. So I am wondering to share with newbie to learn from it and avoid big loss. Beginning of this year due busy on offline job I left trading and thought to hold few coins. And I did it. Once markets became red I though it will be recover that's why I didn't used stop loss. But unfortunately market became more dump and I have loss more than 3X. I am thinking now if I had used stop loss then it might loss only 10%.
If someone want to hold few coins then you can learn from it. Most of exchange now have stop loss feature and you can use it to avoid big loss. Obviously you have choice a exchange for hold any coin for long term. Since we don't know where is the last dip of a coin so it will better to use stop loss. So if you buy a coin for long hold then use stop loss below 10% or 5% from your buy rate. If coin price raise then move your stop loss below 10% or 5% from current rate. If hit stop loss after you buy then wait for another dip and buy it again. Also you can use stop loss for buy. Don't fall in FOMO or FUD.
If you follow this step I think you will not loss big amount of btc if market drop suddenly like what is happening lately. Just don't leave after you buy what I did in past. It's very difficult to recover your fund. There is positive and negetive side for everything so you must need be careful about your fund. You can also share if there are more best policy to HODL.
You're talking here about holding coins on exchanges, which is always the worst option for a number of reasons that most experienced members are all know about. Two reasons why it should be avoided to hold coins on exchages is inability to control private keys ( which would mean that you do not really own what you think you own ), and constant exposure to hacking of exchange. By the way, to mention of phishing attack is another possible vector attack.
We have an expression that 1
BTC is always 1
BTC, so the loss can only be interpreted as a loss of value - not really a loss of coin. You should also know that the market is always going up&down, means if you buy at 8000$ and price is now 4000$ you lost money only if you sell.
Your advice is however good for people who want to trade and use
stop-loss, but in general is not smart to hold cryptocurrency online - because of that we have desktop, hardware, paper wallets, and some others ways of safer storage.
