The reason why so many newbies have missed their steps in Bitcoin is because they have missed the primary approach to avoid getting into the wrong investment, because we all know the risk associated with cryptocurrency for that there is need to clarify one thing which is is burn out of personal research.
Reason why many fail for scam is because they are looking for investment instead of just holding Bitcoin and wait for it value to appreciate organically, there is no doubt that DCA approach is good but then also if a newbie os not careful you could lose along the line of DCA so DCA is out of this discussion, but let dive into something more realistic taking recent happenings with so many investment scam, exchanges ditching off their clients money and so many other scam projects platform and signals that are notable bad actors in the market.
To avoid all this, it become paramount to only abide by one rules which is to keep Bitcoin in your wallet and stop looking for investment that are centralized to reduce your risk.
Just a friendly advice!
I can guarantee you that there is money to be made in every risky corners of crypto investments, I have made a lot of mistakes but what I've gained after is what matters, and it's why I am standing unafraid where many people are scaring away from, so many people get burnt in investment but they don't learn, biggest mistake of all time.
I hold my Bitcoin and I still choose to risk money on other things, with the knowledge I have acquired in the past I am always taking profits when needed and buying more Bitcoin and Ethereum, in this bear market alone, over five altcoins have bring me more than a 10x and I took my profits, invest some back into Bitcoin and this have helped my Bitcoin bag to grow more higher in a short period of time compare to me making money every month and investing part of that into Bitcoin.
I know that not everyone can do this, because it's easier to lose money, but it is something that works for me, I just apply the knowledge I gained from losing money in the past, like having all money in profits but failing to take them out, and also not doing my own research on projects before investing money, that's because I used to rely on what others are saying about a project, like those crazy paid YouTubers.
