if you can teach yourself to only buy when the value-price spread is under 30% its no longer a gut feeling needed to decide when to do trades
Only works on a permabull market.
nah
cant use this tactic on a permabull market.
it works to buy on the dip when the price-value spread goes under 30%
emphasis third time: under 30%
meaning it has to go bear to get to under 30%
buy low sell high is a tactic of repeated trading on a volatile market
thats logic
your 'gamble by guts' only works on a permabull because whatever gutsy number you buy at. you hope it will only go up
buy low sell high is the hope of ups and downs. and then using math and logic to buy at the right dips and sell at the right peaks. repeat. repeat.repeat
You are not getting it. It is not gamble by guts or gut feeling. The point is that no matter how confident or "logical" your are (this does not apply only to bitcoin), at the end you are jumping on a pool of unknown depth. If you do not think so, you have not thought this over enough.
Regarding your system, is full of pitfalls - I would not find time to list. Ok, let´s follow your "system" on a long trend bear market, but not permabear necessarely.
t=1 month spread 100 bitcoin price 1000
t=2 month spread 70 (1st time) bitcoin price 900
t=3 month spread 100 bitcoin price 950
t= 4 month spread 70 bitcoin price 800
t= 5 month spread 100 bitcoin price 850
t= 6 month spread 70 (you buy) bitcoin price 800
t=7 month spread 100 bitcoin price 400 ----- you have lost 4/8
t=8 month spread 100 bitcoin price 300 --- you are down 5/8
t= future (if you know then you have a cristal ball).
etc. So, you can do well with your system as long as the price is rising long term. I see merit on you buying strategy as at least will take the "timing" out of your "gut decission", it is just not purely logic and infalible IMO.
There are quite a few other pitfalls on the "strategy", the problem is that you get a good result due to a secular bull market for BTC, so you think you have a robust system. You don´t.
You also think you have considered the risk because is just a portion of your savings. You have only considered one risk (concentration of investments).
The good thing is that it is making you believe that you are using logic, so no "bravery" involved, etc... to go ahead with it and thus, you think it is not required.
TBH that is something that bitcoin has done for many people who just do not overthink stuff... kind of like having kids or buying a house: if you are too stupid you can´t and if you are too smart (plus lacking balls) there is never a perfect moment.
Good Hodling, I have spent too much time on this tread am I am certain that no system of trading works forever... except perhaps those by Renaissance Technologies.
