You have a good investment plan here but it will be better if the total money spent on gold and silver is not as much as that you spent totally on bitcoin. I have more confident in bitcoin investment than I have in gold and silver.
I get your point. I am tempted to go bigger on bitcoin because bitcoin has a potential to go 100x or more.
However, for bitcoin there are 3 things bothering me:
1) It's either going to millions of euros, or to 0. I think it's 50-50 between the 2.
2) There may be a better moment to purchase it than there is now at 40k. I believe we have not seen the attack of the government on bitcoin yet. I believe there will be organised sell pressure (high taxes for owners, the legal obligation to declare bitcoin holdings, prison sentences for BTC holders..) and this may lead to better buying moments.
3) I can make a mistake with the wallet.
At the moment I am keeping my portfolio at just 15% on BTC because of the second reason. I believe there will be a better moment to buy because we are in front of a global recession worse than 2008. Also if I spread my purchases in time, it's less likely that banks will report me to the tax office.
Just my 2 cents
