I don’t about some people but me i was skeptical at first when my friend introduced me to bitcoin investment. It sounded untrustworthy, it took him a long time before convincing and considering the fact that i was earning little then. But since i got on this train it has been wonderful, so many ups and down since we all know nothing is guaranteed in the crypto world, but so far my time in it has been good.
If you talk about guarantees, I think in any sector there is no one who can guarantee whether someone will be successful or not. Because whether someone is successful or not really depends on their belief and perseverance in doing the work that they already understand themselves, including in the world you mentioned. But if you have started to be interested in Bitcoin and also know how it works, of course it would be better if you could immediately invest in Bitcoin with the funds you currently have. Because Bitcoin can be purchased in the smallest denominations and if you continue to be consistent in buying it for investment, I am sure you will also see results that are more satisfying to you in the future.
