I had over 2800 tickets last week still nothing. I'm almost buying a few hundred tickets every week from the beginning but until now no luck yet. Since there are so many people participating in the lottery so winning chances are very slim so just try our luck every week with a small amount. After all those improvements last week number tickers sold was quite less.
I agree, mate. I'm not going to buy millions of tickets in order to improve my chances of winning a prize. I think millions of sats is a too big amount to put it at risk. Although, it must be noted that the two previous winners have done exactly that. One of them bought 6,276,181 tickets and won 0.68563256 BTC in the round 169 (net win 0.62 BTC). And another one bought 2,120,960 tickets and won 0.46195317 BTC (net win 0.44 BTC).
Nevertheless, like you said, we'll try our luck with small amounts. Let's hope that one day we'll be as lucky as user 13858834, who won 1.23699432 BTC with just 340 tickets in the Lottery Round 164.
