Bitcoin is something very different than stocks, forex or other investments, if you read Satoshi Nakamoto’s whitepaper you won’t bother what the price of bitcoin is. It tends to evaluate by nature, no doubt that a lot of retail investors lately were caught by complete FOMO though.
There are either signs that bitcoin is in a bubble and signs that it has a true use case for daily transactions in countries like Venezuela, Zimbabwe or Greece that help in supporting the price.
Personally I don’t think it’s a bubble but it is indeed overpriced compared to the maturity of its technology in developed countries, I wouldn’t buy it at these prices to be honest, with all time highs broken everyday.
I think the best thing to do is just forget about cryptocurrencies if you are confident and satisfied of your portfolio and come check your investments in a few years from now in order to avoid being driven by emotional investing which could lead to bad choices.
