What you mentioned are types of investments that are profitable, all of which are very worth investing. If I want to choose, I will certainly choose Crypto like Bitcoin to invest. Although all types of investments have risks, indeed in bitcoin the risk is higher. That's because bitcoin has very high fluctuations so that prices can go up / down at any time in any amount, so the risk of receiving losses is huge. But this can also produce big profits, and this is what I like. But if you want a long-term investment, real estate is a very recommendation.
