Total sum transferred closes to 0.004 BTC. Of course it's hard to loose even one Satoshi without a reason. But it is always better to be safe than sorry. Before initiating any transactions with crypto I've purchased hardwallet. All of them have decent support and educative sources. That may help a lot if studied thoroughly. Very strange thing to me was - your link which I couldn't follow with Error 403. Some problems with server? I could manage only by copying transaction hash and forwarding it to other service.
