However, in my last post I expressed my disappointment with centralized exchanges, my unwillingness to continue using them and thankfully I got suggestions mainly endorsing Bisq, of which I've taken time to look into Bisq and other decentralized exchanges and observable is the absence of a support team unlike their centralized counterpart. That be the case, what are:
1. The recurring mistakes that could lead to loss of funds?
2. How can these mistakes be avoided. Since it seems like the only remedy.
First thing is that, I commend you for your total departure from altcoin and your will to hold more Bitcoin since Bitcoin is relatively stable in price, and also for your not wanting to trust centralized exchanges with your funds. There is no doubting the fact that having your wallet with your keys properly stored is the best possible way to have total control over your money and aside from the fact that you will need an exchange to buy bitcoin or use a p2p service to do so. But if you want to hold other coins then you will need to buy them from the exchange and thereafter transfer them into your own wallet and you are advised never to leave your coins on an exchange most especially when the amount is big.
