Not financial advice, but yeah, you can start with a little cash, but not directly with Bitcoin because BTC is not that volatile, and from the current market price, it can only give 1.5x to 2x in the upcoming year. Therefore you have to make some profits by trading in alts and once you make good money, then you can invest them in BTC for more profits.
From the way the OP posted, it’s obvious that the OP is still new to crypto space, you asked the OP not to start trading with bitcoin, because bitcoin is not really volatile in nature, and you recommending the OP to start trading altcoins, which means coins that are highly volatile, don’t you really think that’s wrong, I don’t really think it’s advisable to recommend to newbies to trade coin’s that are highly volatile in nature, the chances of them losing their money is so high, any slight mistake, then their money will be gone which is really a bad one.
If I will be advising any newbie to trade, then I will recommend they trade with a little amount of money, and they should focus on coins that are less volatile, even if they will be switching to coins with high volatility later in the future, then they should start with coins with low volatility, so I will say trading bitcoin and investing in bitcoin is still the best to me, because the chances of losing money are less.
I know everyone’s opinion is different, but I always prefer when newbies invest in bitcoin rather than trading it. Some people do think they won’t be making much money if they hold, but I don’t really agree with that, just imagine the profits that people who bought bitcoin when it dumps to around $15k will make if they are still holding up till now, so I do recommend people hold.
