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?
So, are you expecting to be the next rich person by investing in the bitcoin? Bitcoin will not able to give you the same like what already received by early adopters of bitcoin.
You have been very late now. Think about that. 1 bitcoin is not enough to make you become a new millionaire and you shall wait for another decade to see that happens.
Those who have become early adopters being rich from invest during the early phase then you should learn from what they have done. Try to search for a potential token/coin in the market that may possible to go up as big as what bitcoin done before.
That's the most difficult part.
