For me, it's hard to level my trust in BTC using 0 to 100 since I only invest in what I can afford to lose so i'll say it's around 60-100. I don't know for others on what number they will use since we all did the same which is invest what we can afford to lose. To be honest, I don't rate my trust in BTC because I don't think I can level it myself and one more thing, I don't think it's because of those two that it is the factor that will change the overall level of trust we have on BTC because Bitcoin had already existed and been used many times before it existed. I agree with the above post that we shouldn't dwell so much on our level of trust in Bitcoin.
Aside from the estimated waiting time for Bitcoin investment, I have 100% trust in Bitcoin when it being pit at comparison with Altcoin such as Defi as mentioned by the ops, a lot of times, we tend to bring Bitcoin down by trying to compare Bitcoin with other project and coins, but that is a wrong assumption and class comparison for bitcoin and should be avoid in any discussion because when it comes to trust, there is no level ground between Bitcoin or any altcoin no matter the hype that may have been created around those coins or project.
So for me, bitcoin all the way and I want to advise anyone most especially newbies to take such high risk as to hold Defi tokens for the long term based on just promises, but Bitcoin has proven time without number that it is ahead of the games, and investor funds are secured as long as their patient enough to wait.
