I thought that this might help or entertain someone... $8.000 mistake:
Buying 2 Bitcoins around 2010 and losing them.
I think i got instructions to sending them to my wallet but leaving them on the exchange and forgetting the whole thing. Remembering them when I heard about bitcoin in 2016. I contacted the Swedish Exchange and I got an anonymous support answer asking for any codes or information. I probably sent them information enough to steal the coins if they were there. Got an answer that they can't find them.
How to avoid:
Finish what you start. If you have someone you trust who can help you, get help, but if don't then just make sure you follow instructions and don't postpone part of the task until later...
Mistake number 2. Buying one Bitcoin in November 17 for $9.700 on coinbase, depositing it to a third party fraud platform for interest.
Bitconneeeeect!
I did some research and knew what people were saying and knew there was a risk, but after testing it with $100 for a few days I decided to do it with my only Bitcoin and bet on it lasting the 120 days it would take until i could get the money out again and leave some of the interest on the platform. Around day 70 when bitcoin lost value their was a fraud exit and I got the bitcoin back in Bitconnect coins that lost their value before I heard of it.
How to avoid:
Only trust yourself with the biggest part of your crypto and put it in cold storage like paper wallets or hardware storage. Don't keep more on third party websites than you are ok with losing. Don't underestimate the risks.
Mistake 3. Paying $2000 network fee for sending a bitcoin from coinbase and $2000 fee for buying on coinbase.
How to avoid:
Maybe fees will be a bit lower from now on but fees to buy crypto on credit card or even through bank transfer are still super high on many places. Sign up on Bitstamp or other cheaper services. Transfer money by SEPA or other deposit that is free. Exchange to bitcoin for much lower fee. Send to where you want it.
Mistake 4: Lost $6.000 or so panic buying when price just went up. Panic selling when price just went down multiple times.
Haha, this is the opposite of what we should do, right? And is often a sign that we are playing with more money than we should play with at one time, so we can't stand the pressure of it maybe losing more value short term or missing out on value going up. Some would call it greed.
Ways to avoid:
1/ Buy crypto long term and send it to a safe cold storage and leave your hardware somewhere where you can't quickly get it and panic sell.
2/ Make a budget of how much you will buy crypto for during the year and split it up to buy once a week, every friday for example for the same amount ever week. And stick with the plan. Now if it goes down into a dip and stays there for long, you know that it was only a bit of your money that lost value and you will buy into the dip with the rest of your money and make money when it goes up again.
3/ There are more ways to calm down, like looking at 10 year graphs when close to panic and realizing that this dip will probably make no big difference in a 5 year or 10 year span. As long as you are saving long term and not investing money that you may need soon. If you are, please consider using option 2.
4/ Also consider stopping your investing during a long steep bull run spike and instead start to take out profit into stable coins since a huge spike may sooner or later result in a 75-95% decline. Or just decide to go with the ups and downs. Hoodle.
5/ Consider that you probably lost way, way more in the last 10 years life by keeping savings outside of crypto for long periods of time than you will probably ever lose by keeping money in crypto.
As long as you don't lose access of your backup phrases, passwords or get your crypto stolen...
Ways to avoid stolen crypto:
Save more than one copy of these things in more than one safe place so it can't all get lost at once.
Split your crypto savings up into more than one cold storage.
Mistakes I got away with:
Not using an authentication app like Google Authenticator for the first year. Use the recommended security apps that are available to be safer.
##I guess that's what I have today.
I'm still making some of these mistakes though, like investing too much at one single time, so I might be back later...
