Safer bet would be to invest in BTC after next big dip sub $10K
How is that not a gamble too? At least with video cards, the investment can only lose half of it's value.
Maybe I formulated that sentence wrong, I meant to say that if you want to put some money in crypto you can drop same amount of money with lees energy and time if you buy the coin in the first place.
We know how BTC story goes, only 1% of human mankind using it currently, at the same time flow of BTC is lower and lower after every halving, by the end of this year we should have some new regulating laws across EU that will finally make path for corporate money to go in BTC full speed ahead not only dip in toe finger but completely. That looks as something worth investing from the current perspective, if path stays clear from obstructions from governments.
Video cards can lose only half?
It can lose much more if you buy at the top of mining cycle, and sell in the bear market after new generation goes on the shelf + price of electricity
Keep in mind that you cannot expect same pattern like we had with Nvidia 10xx and AMD 5xx, 4xx in this cycle where people sold old stuff higher then they paid them in 2017-2018.
I hear a lot of noise from youtubers about accumulating cards and sell them on new cycle, that seems like using last cycle pattern that could easily be complete wrong path especially if asic mining prevail completely.
