Nothing is certain in crypto currency and basically I don't enjoy telling people to invest in bitcoin and just as you hoped and predicted that he can make double of the £50 on one year, did you also think of the possibility of not making that amount as we can see that the market has been struggling for over a year now and no one, I mean absolutely no one knows when the market might spike but rather we invest based on hopes and predictions and rather than throw all your money into bitcoin, it wouldn't be a bad idea to diversify and keep trying your luck with some portion in the bonds.
If you think you will invest, just look at the https://fintechguruji.in/shiba-inu-coin-price-prediction-forecast/ and other cryptocurrencies here.
Goodluck.
