most of these currencies listed in OP are not "undervalued" since are available for trading since years and it's very hard they can have another big pump in upcoming years.
Of course I am also bullish with bitcoin and ethereum, but I am not sure about BNB since centralization aspect could have a negative impact for further developments.

I don't think there is any strategy that can be adopted for winning roulette. you can just optimize your loss and try your luck.
Martingale or other strategies could be a serious threat since it's very easy get a losing streak...

per quanto possa essere reale o meno questo investimento, non viene meno il passato controverso di questa applicazione... ed il rischio associato con questo tipo di attività (P2P lending sono praticamente tutti scam).

oltre a questo "rischio" in questo caso si aggiunge il ruolo degli amministratori/piattaforma che è chiaramente legato ad uno scam.

Invito a fare MOLTA ATTENZIONE, non solo per questi ricavi che rasentano la soglia del ponzi ... o per il solito adagio "not your keys not your coin" .... ma anche perchè  Vauld.com è il rebranding di "Bank of Holders" un ponzi MLM lanciato in india che ha già scammato ed è ben noto.... (anche articoli del financial times).

Invito anche a fare un minimo di "due-diligence" quando postiamo certe cose, perchè non tutti hanno capacità e competenze per beccare uno scam con una semplice ricerca su google....

In realtà in passato hanno fatto un token e una ICO che è finita in SCAM!

Definitely not!
It's not just matter of virus and restrictions but this is something really different because nowadays we have bigger and bigger infrastructure (and website) that could manage easily a wave of new gamblers!
Probably COVID19 has just "push up"  development of online betting/casino, giving fuel to a sector that was already growing massively.

more than 24 hours passed and still no answer to my email/request of password reset... it could be possible receive an update or a deadline for solving this issue? thanks in advance

bump! feel free to make an offer or request more information!

This is why, in the same message, I have also suggested to have a look on glacier protocol since all of these aspects are well explained even for a newbie
People have problem even with hardware wallet, so I think it's always better understand the "basics" behind creating a new wallet and safely storage of private keys .

ciao, cosi a pelle ci starei lontano un paio di metri... non esiste alcuna vincita, non esiste alcun premio e esistono tanti modi per frodare gli utenti.

Quando gli scammer promettono queste vincite in generale il sito che utilizzano è abbastanza "scam friendly".
Un paio di dettagli fanno capire che l'exchange in se è molto rischioso (anche perchè voglio dire ne abbiamo decine e decine che offrono servizi e sicurezza...)

I am not able to login anymore on betnomi, plus I am not receiving the email for reset password (despite site confirmed that is registered and they give a message that has been sent).
It could be possible receive some assistance? It's one of the first time that I am playing on this website....

It's very hard achieve a profit with altcoins. I have taken some "suggested coins" from this topic
https://bitcointalk.org/index.php?topic=2106360.0 "The next 100x or 1000x coin",
(where people trying to guess/suggest the coin that could receive a big pump during end of 2017 early 2018)

At December 2017, it means after 3 years, I get following results:
13,18% Reported a positive evaluation.
10.83% Reported a 0 (total loss)
the others just negative results (prices go down).

Despite the market has not been bullish, most of crypto have realized a negative profit, and positive results have been seen just after years of "holding". I think it's very hard find a new gem, this is why generally I continue to buy just bitcoin.

Hardware wallet are definitely cool and very easy for storing crypto currencies... but before you buy one you should take a couple of minutes for read more about a safe storage with just a ... paper wallet! Since https://glacierprotocol.org/docs/before-you-start/overview/ glacier protocol is enable to explain all steps that you need to perform before create your private keys and safely store your coins.
I am not saying don't buy an hardware wallet, just look also a very cheap solution that could be easily adopted by anyone...

I am not saying that this is a ROI that you can't achieve, but you should pay a lot of attention to scam and shi*coins before risking in investment.
Quick ROI means also high risk! It's full of new coins listed and good project but is always difficult make a wise choice.
About NFT and similar you can find some hiding gem, but the market is very big, and best pieces have been bought for higher amount then 10K...

Casinos are working off chain so it's really hard to identify these type of bets "directly" or in a classic way.
If these bets are clearly identified like with a disclaimer or a comment well highlighted I don't see any bad initiative by the streamers.
Differently is the situation of scam attempts, where people are deceived to invest in a rigged system and streamer is aware about the scam involved.

I love competitions but I am feeling ok even while playing alone. In the past I have taken part in a series of competitions hosted by direct bets and I have also win a couple! Indeed there is a lot of time and effort required for a good result. High payout/prizes, competitors and generally not easy tasks give a special emotion for that competitions. I have not participated anymore in other games since then, I don't know if anyone will launch a nice tournament like these.

I made an experiment taking some "suggested coins" from this topic
https://bitcointalk.org/index.php?topic=2106360.0 "The next 100x or 1000x coin"
where people trying to guess/suggest the coin that could receive a big pump during end of 2017 early 2018.
Chainlink has been one of the best performer according my blog post dedicated to the coin! Take a look if you like.

I have placed a couple of bets in some esports like fifa games but each time with no luck
I think that like any other sport you need to study well the players, conditions, single matches. for sure "combine" are always possible since it's a sport like any others.
For sure after next Olympics games (that seems want launch the first esports competitions), we will see more and more of these esports becoming very popular in western countries...

What is your time frame? If you're looking for a simple speculation pay attention since you're so newbie and this world is full of sharks, whales, scammers... best time for investing depends in your wallet. if you have enough money to risk, ok go for. but if you are just going to risk your life saving and you don't have a "plan-b" it's better you avoid this chance.
