An interesting fact is that it took only one year for BTC to grow from $3000 to $60000, and the 20 times increase was absorbed in 12 months.
Lol that's pretty interesting if you didn't even take a look at shiba inu or doge coin about how these coins were growing more than 20 times. Both have been going up just like thousands percents in last year. I meant you must also try to take a look at another token as well. Bitcoin is good but altcoins are always offering more return compared with bitcoin. It can be seen from what happened with shiba and doge coin.
Some altcoins can offer better profits than what bitcoin offers during the same time span, but it is a mistake to think that all the altcoins in the market can offer that kind of performance, the OP already has a capital that is big enough so I do not see the point of taking the risk of investing in a coin like Dogecoin or Shiba Inu, yes the profits can be better but the losses can also be massive, so it is better to take the safest path and just buy bitcoin and be done with it.
