Glad to be of help, bro. I saw you mention /x/ earlier and I get the vibe that you were one of those people lurking there during /x/'s golden age. Comfy times being young and reading original creepypastas and whatnot.
>Do you use any apps for your trades?
Blockfolio is nice for keeping track of what I hold, but I don't do any actual exchanges on phone apps, no.
>Any pitfalls that newfags may fall into that you could warn of?
I get the vibe that you 'get it' so I won't bore you with too many details: the surefire key to success is to buy and hold. There's no magic to it, although 'holding' might be a lot harder than you think it is when you start seeing gains.
Throw money you can forget about into crypto, and let it sit for a while.
Stick to high volume coins (i.e. popular ones, at least at first), don't follow trends too much - make sure you're getting into something with decent tech AND marketability (think general image, brand, meme-worthiness, etc.).
Don't think that this is a hobby that requires your full attention. It's nice to celebrate on Veeky Forums, the board is fun, but you're quite safe just letting your coins wait for you. Don't waste your time checking charts and following hype all the time.
Don't think of yourself as a 'trader', think of yourself as an early discoverer / adopter, buy some crypto, continue living your life and enjoy the gains.
Welcome aboard (hopefully) and good luck to you too.
Other anons might caution you on this as well but don't feel too rushed either - we haven't even seen the tip of the tip of the iceberg yet. Sooner is better, but we're a long way from the top.
