People seem to have become millionaires in previous bull cycles with modest investments in BTC & ETH. If I invested in 1 BTC, is it enough to make me a millionaire by the next bull run, or are there an elite number of alt coins that could help me safely achieve what BTC & ETH once did?
you should do your own research and look for projects with good potential, and guarantee your investment, you can just ask others for advice, but you should review before investing in the project.
