I totally agree that IOTA is a real long-term HODL coin; problem is though how securely we can hodl it

I constantly read about wallet issues; while keeping it on exchanges bitfinex or the few other asian ones that adopted it now, also looks shady.
Any tips?
The wallet is the safest place.
Get the latest wallet (2.5.4), create a random, secure seed, make a backup of your seed and don't share your seed with anybody ever.
Follow all the updates regarding the wallet. Whenever a new wallet is released, download it and check your balance.
You can receive multiple times on an address as long as you don't send anything. If you are unsure, just generate/attach a new address for receiving.
When a transaction is stuck, change node, probably change the curl implemention, set min weight to 14 and reattach every 30 minutes.
There are wallet issues, yes, but 99,99% are/were because users didn't know how to handle the wallet correctly. In addition to that, you only hear of people having problems with the wallet. Those (thousands of users) that don't encounter any problems with the wallet won't raise their voice
