Having an interest in bitcoin and wanting to invest in it can, in my opinion, be a wise decision, as the cryptocurrency has seen tremendous growth in recent years. On the other hand, I don't think it's a smart idea to invest your savings in order to purchase bitcoin. I believe that you should keep the money from investments and savings separate because, given the volatility of the market, we can never predict what will happen in the long run—it will either rise or fall. Instead of giving it everything we have and considering bitcoin to be our main source of income, we should just consider it to be one of our financial assets.
Well, how do you think personal savings should be invested, then? Personally, I would invest all my savings in Bitcoin, especially right now that BTC's price is rising consistently week after week, as we are close to the next halving which is expected to happen in April. It's an once in a lifetime opportunity which shouldn't be wasted by anyone. I'm fully confident on this bull run and I wouldn't bother risking everything on it, even because I'm not aware of another investments which have the same profit potential of Bitcoin, while delivering similar reputation and security levels.
I would only change my stance on this matter if I had a considerable portfolio to purchase an interesting property, house, apartment or piece of land. But without enough funds to do so, Bitcoin remains as the best investment alternative for small and medium size investors.
Moreover, since OP is on the beginning of his professional life, the risk for him to invest in BTC isn't the same of a retired elder investing his life savings on it, which took decades to be achieved. What means there can't be margin for mistakes anymore at this point of life.
