I'm also into this crypto market and prices are very unpredictable. So what I do is I buy and sell regularly but never sell at a loss means I buy monthly or weekly in small quantities whenever I get some extra money and sell some portion of it when I make around 20 to 30% profit and wait for some more time.

Luckily I didn't buy any bitcoins above 15K because I was worried that prices went up super fast and waiting for it to correct but it has corrected too much now. I too have some coins which bought above 10K but I believe prices will again go up so I will just wait.

Yep, very smart move.  Honestly it's the same with a majority of investment, but please make sure you realize that Bitcoin is not an "investment" of a certain company, but rather an asset/currency that you are the only person who is responsible for in terms of it's corresponding private key.

As for me personally, I like to make routine "investments" into whatever I feel is better at the time and hold until green no matter what.  Whatever you invest consider that money gone, period.  So for me as an example, I throw in money into crypto at times when I feel the crypto market is feeling bullish, and then I throw in money into stocks when I feel the stock markets are bullish, etc.  Only sell when you are sure about the mid to long term outcomes look dire.

youre not alone, all people now think twice about investment and keep profit in bitcoin. also when faomus social media like facebook and twitter banned crypto activity, it will more seriously

nah, just because price is falling and you didn't expect it, that doesn't mean it is pure luck. it just means you were not experienced enough to expect a drop and you were definitely not experienced enough to make profit from that drop.
otherwise the rest of the traders with experience are enjoying their profit these days too.

Pure luck is applicable in the shitcoins and not the bitcoins! Shitcoins are the one who can get hampered a lot and sometimes they go scam too, so you cant rely on them but your luck, where you should hit the right shitcoin and gain the profits.

Bitcoin? Oh yeah its real thing and guess what it is still in existence from the 2009 year and none of them complain about it that its ponzi or scam as everyone is getting their share of pie.

Getting your invested money grown is just matter of time through which bitcoin will raise to value which is greater than your entry point. There is no luck in that because it is sure thing as wavy patterns in the bitcoin is very common.
